[R] need help with strsplit function

[njhuang86]

Hi, if I have this string: "a.b.c.d" and I use this function:
unlist(strsplit("a.b.c.d", "\\.")), I get this as my output: "a", "b", "c",
and "d". Is there a way to just split on the first period so I obtain only
two pieces like: "a" and "b.c.d"? Anyways, thanks in advance!
