R CMD check
Dear R-Group,
I have a function that sorts a data frame and oneo of the lines in the
function is:
vars <- unlist(strsplit(formc, "[\\+\\-]"))
The function works fine and the above line is always reached. However, when I
include the function in a package and run "R CMD check pkgname" it gives this
error message:
'\+' is an unrecognized escape in character
