as.unordered function

Convert to unordered factor

Unordered analogue of base R's as.ordered. Will convert x to an unordered factor; unlike as.factor(), this will convert ordered factors to unordered factors.

as.unordered(x)

Arguments

• x: Object to convert to unordered factor

Returns

x as an unordered factor

Examples

# Convert an ordered factor to unordered
as.unordered(gl(5,1,ordered = TRUE))

# If level order is pre-specified differently from default alphabetical order
# then the ordering will be retained
as.unordered(ordered(c("a", "b", "c"), levels = c("c", "a", "b")))

# Otherwise the vector will be converted to an unordered factor with levels
# in the default alphabetical order
as.unordered(c("c", "a", "b"))

# Note that coercing integer values will sort the values to use as the levels
as.unordered(4:1)
