Colleagues,
I have some text:
TEXT <- c("a", "bb;ccc", "dddd;eeeee;ffffff")
I want to retrieve the portion of each element before the first
semicolon. I can split each element using strsplit:
SPLIT <- strsplit(TEXT, ";")
This yields:
> SPLIT
[[1]]
[1] "a"
[[2]]
[1] "bb" "ccc"
[[3]]
[1] "dddd" "eeeee" "ffffff"
Now I need to access the [1] portions of [[n]] - ("a", "bb",
"dddd"). I suspect that sapply is the correct tool here but the
syntax eludes me. Can anyone direct me to the correct syntax?
