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!
Try this:
> strsplit(sub("\\.", "*", "a.b.c.d"), "\\*")
[[1]]
[1] "a" "b.c.d"
The inner sub() replaces the first '.' with a '*' allowing you to
split on the unique character. You can modify the replacement
character as your data may actually require.
