Is it correct that one does not need to escape special characters such as
"*" (are these
properly called metacharacters) inside []. If so, what is the logic to this?
mytest <- "he*llo"
sub("[*]","",mytest)
sub("\\*","",mytest)
[] is easier to read for me than \\. Is this what people tend to use?
Thanks.
