Let say I have following code: > gsub("[',]", "", "'asd'f") [1] "asdf" This is perfect. However I am having problem if I include "" (i.e. the double quote) in the first argument as the pattern search: > gsub("[',"]", "", "'asd'f") Error: unexpected ']' in "gsub("[',"]" What is the right way to include the 'double quote' in the search field?
