[R] Extract pattern from string

[Justin Haynes]

take a look at the structure of what Sys.time returns.

str(Sys.time)

and now at ?strptime!

> format(Sys.time(),format='%d-%H-%M-%S')
[1] "15-09-55-55"

> format(Sys.time(),format='%Y')
[1] "2011"
> format(Sys.time(),format='%m')
[1] "11"

Hope that helps,

Justin
