Hello.
Sorry for this very basic question but I didn't find (of didn't understand)
the answer either in the help or in the online guide.
I have a string, let's say "hello". I want to know if there is some
character in it, let's say an 'o'.
I tried
> charmatch("o", strstplit("hello",""))
but it gives NA (why??)
Thinking it may be a type problem, I tried
> charmatch("o",as.character(strsplit("hello","")))
but it gives NA too (why???)
So how can I know if a given string contains a given char?
Thanks!
