file=R/adjust.R,line=184,col=7,[scalar_in_linter] Use == to match length-1 scalars, not %in%. Note that == preserves NA where %in% does not.

file=R/dist.R,line=917,col=18,[unnecessary_concatenation_linter] Unneeded concatenation without arguments. Replace the "c" call by NULL or, whenever possible, vector() seeded with the correct type and/or length.

file=R/dist.R,line=946,col=20,[unnecessary_concatenation_linter] Unneeded concatenation without arguments. Replace the "c" call by NULL or, whenever possible, vector() seeded with the correct type and/or length.

file=R/dist.R,line=1147,col=31,[redundant_equals_linter] Using == on a logical vector is redundant. Well-named logical vectors can be used directly in filtering. For data.table's `i` argument, wrap the column name in (), like `DT[(is_treatment)]`.

file=R/dist.R,line=1248,col=14,[numeric_leading_zero_linter] Include the leading zero for fractional numeric constants.
