as_chr: Convert to character

In decisionpatterns/coercion: Utilities for Coercing (and Parsing) Values Between Types, Modes and Classes

Description

Convert to character

Usage

as_chr(x, ..., na)

## Default S3 method:
as_chr(x, ..., na)

## S3 method for class 'logical'
as_chr(x, true = "TRUE", false = "FALSE", na)

Arguments

x	logical vector
na	string; value to set for NA (missing values)
true	string for TRUE value
false	string for FALSE value

Details

as_chr converts x to character. It is smarter versions of base::as.character().

The default method wraps base::as.character().

The method for logical values allows for mapping TRUE, FALSE and NA values to values to Using non-default values fortrueorfalse' results in non-invertible transformation. (true="T", false="F" is also invertible )

This also allows for setting TRUE or FALSE values to NA

See Also

• base::as.character() which is a primitive method for which S3 classes cannot be defined.

• na.tools package for functions that replace and impute NA in vectors.

Examples

  v <- c(TRUE, FALSE, NA )
  as_chr(v) 
  as_chr(v, "T", "F" )
  as_chr(v, true="T", false=NA )
