regex pattern assistance
WOW!!! What can I say 4 answers in less than 4 minutes. Thank you everyone. If I can't make it work now I don't deserve to. btw. the strsplit approach wouldn't work for me as: a) I wanted to play with regex and b) the location isn't consistent. Nice to see email support still works, not everything has moved to linkedin and stackoverflow. Thanks again, Tom

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
