Anyway, I still wouldn't mind some advice on character

Thanks.
If so we need a reproducible example of what you are doing.
OK, let's say I have three strings. Str1="abc". Str2="abcd".
Str3="efgh".
I want to compare Str1 and Str2 in such a way that R detects that Str2
indeed contains Str1. I want something that returns a "TRUE" value.
Then I want to compare Str1 and Str3 so that R detects that Str3 does
not contain Str1. I don't want it to give me an error because it can't
find Str1. I just want to get a "FALSE" value. Is there a way to do
this that's less messy than what I came up with? Thanks again.
Str1 <- "abc"
Str2 <- "abcd"
Str3 <- "efgh"
> sapply(list(Str2, Str3), grepl, pattern = Str1)
[1] TRUE FALSE
