[R] gsub and "\"

[jim holtman]

It does have a single \; the printing just shows that it is escaped.
If you 'cat' it to output, you will see:


> gsub("'","\\\\'","abc's")
[1] "abc\\'s"
> cat(gsub("'","\\\\'","abc's"))
abc\'s

Which I think is what you were thinking it would be.  So when you
write it out to a file, it will be correct.
