How to replace '$' sign?

Hello again,

I want to remove "$" sign and replace with nothing in my text.
Therefore I used following code:
gsub("$|,", "", "$232,685.35436")
[1] "$232685.35436"

However I could not remove '$' sign.

Can somebody help me why is it so?

Thanks and regards

The dollar sign is a metacharacter in regular expressions (see ?regex), thus has to be escaped to be interpreted as a literal character:
gsub("\\$|,", "", "$232,685.35436")
[1] "232685.35436"

Hello,

Try

gsub("[$,]", "", "$232,685.35436")

Hope this helps,

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"
