Try
grep( "\\.x$", c("a.x" ,"b.x","a.xx"),value=TRUE)
The $ means end-of-line (while ^ means start-of-line). And special
characters like dot needs to be escaped twice.

dear all,
This is a probably a silly question.
If I type
> grep("x",c("a.x" ,"b.x","a.xx"),value=TRUE)
[1] "a.x" "b.x" "a.xx"
Instead, I would like to obtain only
"a.x" "b.x"
How is it possible to get this result with grep()?
many thanks for your attention,
best,
vito
