Hello,
The following pattern seems to do it.
grep("^Intensity$|^Intensity\\s[^HL]",
c("Intensity","Intensity L", "Intensity H", "Intensity Rep1"))
Hope this helps,
Rui Barradas

Hello,
Banging my head against a wall here ... can anyone light the way to a
pattern modification that would make the following TRUE?
identical(
grep(
"^Intensity\\s[^HL]",
c("Intensity","Intensity L", "Intensity H", "Intensity Rep1")),
as.integer(c(1,4)))
Thank you for your time.
Sincerely, Joh
