[jim holtman]

Here is how to get the number:

> x <- c("channel 1 20120509 153744 00001.ddf", "channel 1 20120509 154744 00001.ddf",
+ "channel 1 20120509 155744 00001.ddf", "channel 1 20120509 160744 00001.ddf",
+ "channel 1 20120509 161744 00001.ddf", "channel 1 20120509 162744 00001.ddf")
> # get the number
> xNew <- sub("^channel 1 ([0-9 ]+).*", "\\1", x)  # notice the space after the '9'
> xNew
[1] "20120509 153744 00001" "20120509 154744 00001" "20120509 155744
00001" "20120509 160744 00001"
[5] "20120509 161744 00001" "20120509 162744 00001"
