Hi all,
I get an error message when trying to replace *+* or *?* signs (with empty
space) from a string.
x <- "asdf+,jkl?"
gsub("?", " ", x)
Error message:
Error in
gsub("?", " ", x) :
invalid regular expression '?'
In addition: Warning message:
In gsub("?", " ", x) :
regcomp error: 'Invalid preceding regular expression'
Your expertise in resolving this issue would be appreciated.
Thanks.
Steven
