'?' is a metacharacter in a regular expression. You have to escape it:
x - asdf+,jkl?
gsub(?, , x)
Error in gsub(?, , x) : invalid regular expression '?'
In addition: Warning message:
In gsub(?, , x) :
regcomp error: 'Invalid preceding regular expression'
# escape it
gsub(\\?, , x)
Try this:
gsub([?], , x)

And if you want to replace both + and ?, here is a suggestion:

Since both ? and + are special regex characters, to do both the
substitutions at once you need to use
