Arguments

x

Character vector, potentially ANSI styled, or a vector to coarced to character.

split

Character vector of length 1 (or object which can be coerced to such) containing regular expression(s) (unless fixed = TRUE) to use for splitting. If empty matches occur, in particular if split has zero characters, x is split into single characters.

...

Extra arguments are passed to base::strsplit.

Value

A list of the same length as x, the i-th element of which contains the vector of splits of x[i]. ANSI styles are retained.
