Description

Put character vectors, columns of a data.frame or list elements as factor if they are character strings or optionally if they are logicals

Usage

factorise(x, logicals = FALSE, ...)

## Default S3 method:
factorise(x, logicals = FALSE, ...)

## S3 method for class 'character'
factorise(x, logicals = FALSE, ...)

## S3 method for class 'data.frame'
factorise(x, logicals = FALSE, ...)

## S3 method for class 'list'
factorise(x, logicals = FALSE, ...)

Arguments

x	a character vector, a data.frame or a list
logicals	logical indicating if logical vectors should also be converted to factors. Defaults to FALSE.
...	optional arguments passed on to the methods

x <- data.frame(x = 1:4, y = LETTERS[1:4], b = c(TRUE, FALSE, NA, TRUE), stringsAsFactors=FALSE)
str(factorise(x))
str(factorise(x, logicals = TRUE))
str(factorise(list(a = LETTERS, b = 1:10, c = pi, d = list(x = x))))
