Shouldn't your "[:digit:]" be "[[:digit:]]"? Bill Dunlap TIBCO Software wdunlap tibco.com

Using R is a grate advantage, thanks for your work.
Using regex under R 3.1.1, Debian 8.6 jessy works fine.
str_detect("16-03-08", "[:digit:]{2}")
[1] TRUE
str_detect("16-03-08", "[0-9]{2}")
[1] TRUE
runing the same code under R 3.3.2 backport, Debian 8.6 jessy gives a
different result. This is also a different computer.
str_detect("16-03-08", "[:digit:]{2}")
[1] FALSE
str_detect("16-03-08", "[0-9]{2}")
[1] TRUE
Is this intended?
My workaround is using [0-9] instead of [:digit:].
Thanks
