问题
I am trying to remove parentheses from a string value in this case this one:
(40.703707008, -73.943257966)
I can't seem to find a post with code that works; I know that this is a very simple task, but I've seen the following links but they either kill all my punctuation or don't seem to work. Below is the codes I've tried. Appreciate the help:

Remove parentheses and text within from strings in R
x = ("(40.703707008, -73.943257966)")
gsub("\\s*\\([^\\)]+\\)","",x)
gsub("\\D", "", x)
gsub("log\\(", "", x)
回答1:
These are metacharacters that either needs to be escaped (with \\) or we can place it in a square bracket to read it as character.
gsub("[()]", "", x)
#[1] "40.703707008, -73.943257966"
