R: extract directory out of a path [duplicate]

Answer 1

You could also use the built-in function basename:

basename(Path)
[1] "7"

Answer 2

You have to add a second pair of \\ to escape the \ to the regex:

> Path <- "123\\456\\7"
> Split <- strsplit(Path, "\\\\")
> Split[[1]][length(Split[[1]])]
[1] "7"
