[R] Regex: just keep the money and not the description

[Omar André Gonzáles Díaz]

Hi R users, I have a character vector with 2 numbers: old price, new
price. The problem is that some rows (4,23, for example) contain a
little description of the product, which I don't need.

I've tried a lot of thins, like this one:

TV_Precios3 <- gsub("^S ^[0-9]{2}\\$","",TV_Precios2)

Without result. Any help is welcome.

After that I want to separate them with colsplit (have this solved)
based on "S/.".



head(TV_Precios3,50)
