Re: [Rd] Named backreference in gsub()?
strapply in the gsubfn package matches a regular expression and passes
each back reference as a separate argument to the indicated function,
in this case paste. Any number of back references may be used. Here
is an example where there are more than 9:

[[1]]
[1] "a b c d e f g h i j"

[Rd] Named backreference in gsub()?
Hi, I'm running out of the *numbered* backreferences \\1, \\2, ..., \\9 for gsub(). Does R support *named* backreferences, and if so, what is the syntax? Thanks Henrik __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
