Subject: [Rd] gsub + backslashes

Dear developeRs,

I thought that backslashes can be escaped in the usual way (and I think I 
did this before) but I can't see why

R> gsub("\\", "x", "\alpha")
Error in gsub(pattern, replacement, x, ignore.case, extended, fixed, 
useBytes) :
         invalid regular expression '\'

gives an error. Or am I just blind?

Best,

Torsten
