concat.split.expanded: Split Concatenated Values into their Corresponding Column...

In mrdwab/splitstackshape: Stack and Reshape Datasets After Splitting Concatenated Values

Description

"Expand" concatenated numeric or character values to their relevant position in a data.frame or data.table or create a binary representation of such data.

Usage

cSplit_e(data, split.col, sep = ",", mode = NULL, type = "numeric",
  drop = FALSE, fixed = TRUE, fill = NA)

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.
mode	Can be either "binary" (where presence of a number in a given column is converted to "1") or "value" (where the value is retained and not recoded to "1"). Defaults to "binary".
type	Can be either "numeric" (where the items being split are integers) or "character" (where the items being split are character strings). Defaults to "numeric".
drop	Logical. Should the original variable be dropped? Defaults to FALSE.
fixed	Used for base::strsplit() for allowing regular expressions to be used.
fill	Desired "fill" value. Defaults to NA.

Value

A data.frame or data.table depending on the source input.

Examples

temp <- head(concat.test)
cSplit_e(temp, "Likes")
cSplit_e(temp, 4, ";", fill = 0)
 
## The old function name still works
concat.split.expanded(temp, "Likes")
concat.split.expanded(temp, 4, ";", fill = 0)
concat.split.expanded(temp, 4, ";", mode = "value", drop = TRUE)
concat.split.expanded(temp, "Siblings", type = "character", drop = TRUE)
