Convert a vector to boolean/logical

Usage

to_boolean(x, ...)

# S3 method for class 'logical'
to_boolean(x, ...)

# S3 method for class 'numeric'
to_boolean(x, true = 1, false = 0, na = NULL, ...)

# S3 method for class 'integer'
to_boolean(x, true = 1L, false = 0L, ...)

# S3 method for class 'character'
to_boolean(
  x,
  true = c("TRUE", "true", "T", "t", "YES", "yes", "Y", "y"),
  false = c("FALSE", "false", "F", "f", "NO", "no", "N", "n"),
  na = NULL,
  ...
)

# S3 method for class 'factor'
to_boolean(x, ...)

Arguments

x: A vector of values
...: Additional arguments passed to methods
true: A vector of values to convert to TRUE
false: A vector of values to convert to FALSE
na: An optional vector of values to convert to NA; if set, an error will be thrown when any values in x are not matched to true, false, or na.

Value

A logical vector of equal length as x.

Details

to_boolean.integer() is passed to to_boolean.numeric() with integer-specific true and false defaults. to_boolean.factor() converts the factor levels via to_boolean.character().
