Dear guRus,
I am trying to replace "~" by "$\sim$" for TeX. However, I can't get the
backslash to work. I would like to turn "DV~IV" into "DV$\sim$IV".
sub("~","$\sim$","DV~IV") => "DV$sim$IV"
sub("~","$\\sim$","DV~IV") => "DV$sim$IV"
sub("~","$\\\sim$","DV~IV") => "DV$sim$IV"
sub("~","$\\\\sim$","DV~IV") => "DV$\\sim$IV"
Alternatives 1 and 3 also yield warnings about unknown escape sequences
(no surprise there). I have been unsuccessfully searching the archives.

Thank you all for your time!
Best regards

You want door number 4 because when the double escape is cat()'d to the
.tex file, you get:
> cat("DV$\\sim$IV", "\n")
DV$\sim$IV
which is what you want latex to process.
