Subject: How to replace '$' sign?
In-Reply-To: <CA+dpOJkF9-+3r0uNMZ3sjNJAKW1eKt3MW+7AMrQ08wQfkyi9eQ@mail.gmail.com>
Hi,
If you just want to remove the $, it must be escaped because $ is a
special character in regular expressions.
> gsub("\\$", "", "$232,685.35436")
[1] "232,685.35436"
But it looks like you actually want to remove both $ and ,
Modifying your code:
> gsub("\\$|,", "", "$232,685.35436")
[1] "232685.35436"
Or my preferred idiom:
> gsub("[$,]", "", "$232,685.35436")
[1] "232685.35436"
