This is hopefully a simple question. I am trying to escape single quotes like so: abc's >> abc\'s However, I cannot find an easy way to do that with gsub: gsub("'","\\\\'","abc's") # returns "abc\\'s" How can I get a single \ in the output? Thanks, Sean
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. On Wed, Jul 9, 2008 at 11:49 AM, Sean Davis <sdavis2 at mail.nih.gov> wrote:> This is hopefully a simple question.

It's just that when it's prented on the screen, the internal "\" is printed as "\\": nchar("abc\\'s") # [1] 6 nchar("abc's") # [1] 5 Quite how you get it to be displayed as "abc\'s" is another matter, and I don't have an answer to it!
