Hello,
I don't believe you need an extra package for that. Try
sub("\\/mnt\\/AO\\/AO Data\\/([-[:alnum:]]*)\\/.+", "\\1", x)
or, with package stringr,
str_match(x,"\\/mnt\\/AO\\/AO Data\\/(.+)\\/.+")
Hope this helps,

Hi,
Can anyone please assist.
given the string
x<-"/mnt/AO/AO Data/S01-012/120824/"
I would like to extract "S01-012"
require(stringr)
str_match(x,"\\/mnt\\/AO\\/AO Data\\/(.+)\\/+")
str_match(x,"\\/mnt\\/AO\\/AO Data\\/(\\w+)\\/+")
both nearly work. I expected I would use something like:
str_match(x,"\\/mnt\\/AO\\/AO Data\\/([\\w -]+)\\/+")
but I don't seem able to get the square bracket grouping to work
correctly. Can someone please show me where I am going wrong?
Thanks,
Tom
