cut_decreasing {dvmisc}

Cut with Decreasing Factor Levels

Description

Convenience function to get decreasing factor levels from cut. Currently requires specifying breaks as vector of cutpoints rather than number of desired intervals.

Usage

cut_decreasing(x, breaks, include.lowest = FALSE, right = TRUE, ...)

Arguments

x, breaks, include.lowest, right

See cut. specifying number of intervals is not currently supported).

...

Arguments to pass to cut.

Value

Factor variable.

Examples

# In mtcars dataset, create 3 mpg groups
table(cut(mtcars$mpg, breaks = c(-Inf, 15, 20, Inf)))

# Repeat with cut_decreasing to get factor levels ordered from high to low. 
# To match cut here, need to specify right = FALSE
table(cut_decreasing(mtcars$mpg, breaks = c(Inf, 20, 15, -Inf), right = FALSE))

# You can specify breaks from low to high, but then include.lowest and right 
# arguments get confusing
table(cut_decreasing(mtcars$mpg, breaks = c(-Inf, 15, 20, Inf), right = TRUE))
