Splitting Strings

strsplit is used to split a string into substrings:

> unlist(strsplit("abc def ghi jkl", " "))
[1] "abc" "def" "ghi" "jkl"

> unlist(strsplit("abc,def:ghi.jkl", "\\.|,|:"))
[1] "abc" "def" "ghi" "jkl"

The split pattern is a regular expression (hence the \\. is required to quote the full stop).
