Description

Takes a column in a data.frame or data.table with multiple values, splits the values into a list, and returns a new data.frame or data.table.

Usage

Arguments

`data`	The source `data.frame` or `data.table`.
`split.col`	The variable that needs to be split (either name or index position).
`sep`	The character separating each value. Can also be a regular expression.
`drop`	Logical. Should the original variable be dropped? Defaults to `FALSE`.
`fixed`	Used for `strsplit` for allowing regular expressions to be used.

Examples

temp <- head(concat.test)
str(cSplit_l(temp, "Likes"))
cSplit_l(temp, 4, ";")

## The old function name still works
str(concat.split.list(temp, "Likes"))
concat.split.list(temp, 4, ";")
concat.split.list(temp, 4, ";", drop = TRUE)
