Coerce a Factor Object into a Vector of a Given Mode

as.vector.factor

Description

This method implements the as.vector generic funcion for factor objects. It returns a vector that is the result of applying the appropriate as.* function to the argument. See the description of the mode argument for a list of supported storage modes.

Usage

as.vector.factor(x, mode = "any")

Arguments

x	a factor object.
mode	the result mode. It supports the following: list integer double numeric (equivalent to double) complex character, any (equivalent to character), logical, and expression. Any other mode generates an error.

Value

a vector of the specified mode.

Examples

x <- factor(c("R", "G", "B", "R"))
as.vector.factor(x, mode = "any")
# [1] "R" "G" "B" "R"
as.vector.factor(x, mode = "list")
# [[1]]
# [1] R
# Levels: B G R
# [[2]]
# [1] G
# Levels: B G R
# [[3]]
# [1] B
# Levels: B G R
# [[4]]
# [1] R
# Levels: B G R
as.vector.factor(x, mode = "integer")
# [1] 3 2 1 3
as.vector.factor(x, mode = "double")
# [1] 3 2 1 3
as.vector.factor(x, mode = "numeric")
# [1] 3 2 1 3
as.vector.factor(x, mode = "complex")
# [1] 3+0i 2+0i 1+0i 3+0i
as.vector.factor(x, mode = "logical")
# [1] NA NA NA NA
as.vector.factor(x, mode = "character")
# [1] "R" "G" "B" "R"
as.vector.factor(x, mode = "expression")
# expression(3L, 2L, 1L, 3L)
## Not run: 
as.vector.factor(x, mode = "foo")
## Error in as.vector(x, mode) : invalid 'mode' argument

## End(Not run)
