Please read ?regex, where it says:
" Any metacharacter with special meaning may be quoted by preceding it
with a backslash. The metacharacters in EREs are . \ | ( ) [ { ^ $ * +
?, but note that whether these have a special meaning depends on the
context. "
So use:
sub("\(\)","", names(dataFrame))
instead.
