This R package contains helper functions for working with the MySQL database for the Learning To Talk project.
Install the devtools package. Then install the package from GitHub.
install.packages("devtools")
devtools::install_github("LearningToTalk/L2TDatabase")Connections to the database are managed by .cnf files. We use these files so that login credentials and connection information are not hard-coded into analysis scripts.
This package provides the helper function make_cnf_file() which creates a .cnf file from login and connection information. Once the file is created, we can just point to this file whenever we want to connect to the database.
library("L2TDatabase")
# initialze a cnf file using all default (empty) values
make_cnf_file(dest = "./my_connection.cnf")
#> Writing to ./my_connection.cnf:
#> [client]
#> user=
#> password=
#> host=
#> port=3306
#>
#> [rs-dbi]
#> database=
# all values filled
make_cnf_file(
dest = "./my_connection.cnf",
user = "tj",
password = "dummy-password",
db = "my_db",
host = "localhost",
port = 3306)
#> Writing to ./my_connection.cnf:
#> [client]
#> user=tj
#> password=dummy-password
#> host=localhost
#> port=3306
#>
#> [rs-dbi]
#> database=my_dbWe use the function l2t_connect() to connect to the database. This function takes the location of a .cnf file and the name of the database and returns a connection to the database. By default, l2t_connect connects to the l2t database.
# connect to the database
l2t <- l2t_connect(cnf_file = "./inst/l2t_db.cnf", db_name = "l2t")This package is built on top of dplyr, a package for dealing with data stored in tables. dplyr provides a set of tools for working with remote data sources --- that is, data in databases, usually on other computers. Conventionally, to access data in a database, one has to write special queries to retrieve information from the database. dplyr lets us write R code for our queries, and it translates our R code into the language used by the database. (See the dplyr vignette on databases for more information on how to work with remotely stored data using dplyr.)
In the terminology of dplyr, a remote source of data is a src, and a table of data is a tbl. To connect to a table of data, use tbl(src, tbl_name). For example, here's how I would connect to the MinPair_Trials table in the database which contains the trial-level data about the minimal pairs experiment.
library("dplyr", warn.conflicts = FALSE)
# use tbl to create a link to a tbl in the database
minp_resp <- tbl(src = l2t, from = "MinPair_Trials")
minp_resp
#> # Source: table<MinPair_Trials> [?? x 13]
#> # Database: mysql 5.6.20 [[email protected]:/l2t]
#> Study ResearchID MinPair_EprimeFile MinPair_Dialect
#> <chr> <chr> <chr> <chr>
#> 1 CochlearMatching 390A MINP_390A69FS3 SAE
#> 2 CochlearMatching 390A MINP_390A69FS3 SAE

#> 8 CochlearMatching 390A MINP_390A69FS3 SAE
#> 9 CochlearMatching 390A MINP_390A69FS3 SAE
#> 10 CochlearMatching 390A MINP_390A69FS3 SAE
#> # ... with more rows, and 9 more variables: MinPair_Completion <chr>,
#> # MinPair_Age <int>, MinPair_TrialType <chr>, MinPair_Trial <int>,
#> # MinPair_Item1 <chr>, MinPair_Item2 <chr>, MinPair_ImageSide <chr>,
#> # MinPair_TargetItem <chr>, MinPair_Correct <int>With dplyr, I can perform all kinds of operations on this table. Here, I filter() rows to keep just the man-moon practice trials and select() a subset of columns.
man_moon_practice <- minp_resp %>%
filter(MinPair_Item1 == "man", MinPair_Item2 == "moon") %>%
select(Study, ResearchID, MinPair_TargetItem, MinPair_Correct)
man_moon_practice
#> # Source: lazy query [?? x 4]
#> # Database: mysql 5.6.20 [[email protected]:/l2t]
#> Study ResearchID MinPair_TargetItem MinPair_Correct
#> <chr> <chr> <chr> <int>
#> 1 CochlearMatching 390A moon 1
#> 2 CochlearMatching 390A man 1
#> 3 CochlearMatching 391A moon 1

#> 9 CochlearV1 301E moon 0
#> 10 CochlearV1 301E man 1
#> # ... with more rowsThis data lives in "the cloud" on a remote computer. That's why the first line of the print out says Source: lazy query [?? x 4].
When we print the data as we did above, dplyr downloads just enough rows of data to give us a preview of the data. There are approximately 12,000 rows of data in the minp_resp table, and this just-a-preview behavior prevented us from accidentally or prematurely downloading thousands of rows when we peeked at the data. We have to use collect() to download data to our computer.
man_moon_practice <- collect(man_moon_practice)
man_moon_practice

#> 9 CochlearV1 301E moon 0
#> 10 CochlearV1 301E man 1
#> # ... with 874 more rowsIn this printout, there is no longer a line specifying the source. Instead, we are told that we have a tibble, which is just a kind of data-frame. The data now lives locally, in our R session. Now, we can plot or model this data like any other data-frame in R.
Take-away: We use dplyr to create queries for data from tables in a database, and we use collect() download the results of the query to our computer.
Information about our participants and their testing data are stored in two separate databases. The first is l2t. This database contains user-friendly, analysis-ready tables of information. l2t is the default database that l2t_connect() uses. This database probably has the information that you need in a ready to use form.
# list all the tbls in the database
src_tbls(l2t)
#> [1] "BRIEF" "Blending_Summary"

#> [25] "Scores_TimePoint1" "Scores_TimePoint2"
#> [27] "Scores_TimePoint3" "Task_Ages"
#> [29] "Task_Ages_Summary" "VerbalFluency"The tables here are queries: Tables that are computed on-the-fly whenever the data is requested. For example, MinPair_Aggregate shows the proportion correct of non-practice trials in the minimal pairs task by participant and by study. (I select() a subset of columns to exclude unnecessary columns like the name of the Eprime file containing the raw data.) The Study and ResearchID are the conventional identifiers for studies and participants.
tbl(l2t, "MinPair_Aggregate") %>%
select(Study, ResearchID, MinPair_Dialect, MinPair_ProportionCorrect)
#> # Source: lazy query [?? x 4]
#> # Database: mysql 5.6.20 [[email protected]:/l2t]

#> 9 CochlearV1 305E SAE 0.5000
#> 10 CochlearV1 306E SAE 0.6667
#> # ... with more rowsThe values in MinPair_ProportionCorrect are not stored or hard-coded but computed on the fly as part of a query. Thus, if for some reason, the trial-level data about the experiment were to change in the database, then the MinPair_ProportionCorrect column would update automatically.
The tables in l2t are queries, so they are assembled by combining information from tables of raw data. The raw-data tables live in the second database (the backend for our queries.) These raw data tables do not contain any of our participant IDs or study names, so they are not user-friendly. You probably don't need to work with the backend of the database, unless you are developing new aggregations of data that are not yet presented in the l2t database.

#> [48] "q_Task_Ages"
#> [49] "q_Task_Ages_Summary"Some of the tables in the backend are not tables of raw data but intermediate, helper queries that are used in the main database. These helpers queries are prefixed with q_. For example, q_Household_Education, q_Household_Maternal_Caregiver, and q_Household_Max_Maternal_Education are a pipeline of calculations that determine the highest maternal education level in each household.
Our eyetracking data lives in eyetracking. I separated it from the other kinds of data because it contains individual frames of eyetracking data, so it houses a tremendous amount of data. One of the tables has at least 10 millions rows of data. The database contains user-ready queries. They are prefixed by q_.
l2t_eyetracking <- l2t_connect("./inst/l2t_db.cnf", db_name = "eyetracking")
src_tbls(l2t_eyetracking)
#> [1] "BlockAttributes" "Blocks"

#> [7] "q_BlocksByStudy" "q_LooksByStudy"
#> [9] "q_MissingDataByBlock" "q_TrialAttributesByStudy"
#> [11] "q_TrialsByStudy"There is also a database norms with some raw-score-to-standardized-score look-up tables for some standardized tests.
Take-away: The data you probably want lives in the default database l2t.
As I've worked on the back-end of the database, I've been using the database comments to describe the data that goes into each table and each field. We can download these comments along with other pieces of information about a table by using describe_tbl(). With this function, we can quickly create a "codebook" to accompany our data.
describe_tbl(src = l2t, tbl_name = "MinPair_Aggregate")

#> 2 MinPair_Aggregate ResearchID varchar(4)
#> 3 MinPair_Aggregate MinPair_EprimeFile varchar(16)

#> 5 MinPair_Aggregate MinPair_Completion date

#> 7 0 NO
#> 8 <NA> YES
#> Description
#> 1 Name of the study
#> 2 Four character form of the participant's Research ID
#> 3 Filename of Eprime output for this administration (minus .txt extension). Source of the data.
#> 4 Dialect version of the experiment (based on Eprime filename)
#> 5 Date the MinPairs experiment was administered. Extracted from XML blob in Eprime txt output file.
#> 6 Age in months (rounded down) when Minimal Pairs was completed
#> 7
#> 8In some queries, the fields are computed dynamically, whenever the data is requested. In the MinPair_Aggregate query, the proportion correct is calculated when the data is requested. Our database system does not let us write comments for these dynamically created columns, so that column has a blank for its description.
We can also download the table-level comments from a database with describe_db(), although these descriptions have a much tighter length limit. Table-level comments are also unavailable for query tables, so they are only useful for raw-data tables.

#> 6 Elision subtest of Comp Test of Phon Processing-2nd edThese two forms of metadata are backed up by the l2t_backup() helper function.
We can download and back up each table in a database with l2t_backup(). The final two messages from the back-up function show that the metadata tables are saved to a metadata folder.
Here's how backing up the backend of the database looks:

This function calls on the mysqldump utility which exports a database into a series of SQL statements that can be used to reconstruct the database. This function is very finicky because it requires other programs to be installed on one's machine.
dump_database(
cnf_file = "./inst/l2t_db.cnf",

dump_database(

We want to use R to migrate existing dataframes into the database, but we also don't want to do stupid things either. Therefore, I've developed conservative helper functions for writing data. These functions work on dplyr-managed database connections. For the purposes of this demo, we will work on the separate l2t_test database.
The function append_rows_to_table() simply adds new rows to a database table.
l2t_test <- l2t_connect("./inst/l2t_db.cnf", db_name = "l2ttest")
# Before writing
tbl(l2t_test, "TestWrites")
#> # Source: table<TestWrites> [?? x 3]

#> 1 2 Hello! 2017-06-21 09:29:50I also have an experimental helper function. overwrite_rows_in_table() which will update existing rows in a table, but this one is not as robust or user-friendly as I would like. In my scripts, I usually have lots of checks on the data before and after using this function to confirm that it behaves as expected.
This package also provides some helper functions for working with our data. undo_excel_date() converts Excel's dates into R dates. chrono_age() computes the number of months (rounded down) between two dates, as you would when computing chronological age.
