partial matching with grep()
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

[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
