Removing title in ggally_cor

[tamas-ferenci]

One would expect that title="" removes the title in ggally_cor. However, the colon and the line break unfortunately remains, see the following reproducible example:

library(GGally)
data(flea)
ggpairs(flea, columns = 2:4, upper = list(continuous = wrap(ggally_cor, title = "")))

Is it possibly to correctly remove the title altogether (i.e., that only a single number remains, and nothing else)?

in ggplot in general argument="" does not "removes" the item .
for that you have element_blank
How the function is written it does not allow to "blank" / remove the title completely

ggally/R/gg-plots.R

Line 345 in 3918c50

title = title,

ggally/R/gg-plots.R

Line 396 in 3918c50

title,

you can rewrite the function in a way that allows to remove it pointers above

Thanks! I could've checked ggally_corrs source code myself, sorry... My original question is perhaps better formulated as a feature suggestion in this case. At first glance it seems that allowing sep to be user-manipulated (i.e., adding it as an argument, keeping its current value as default) is a backward compatible change which would also solve this problem.

ggally/R/gg-plots.R

Line 344 in d13006e

sep = if ("colour" %in% names(mapping)) ": " else ":\n",

I'm bumping this issue, as being able to completely remove the title is a feature request that I would also like.

One way around this would be to make the default title "Corr:\n" instead of "Corr", and removing the ":\n" so that having the title as "" would not add any characers.
