reverse_cut: Reverse Cut

In dvmisc: Convenience Functions, Moving Window Statistics, and Graphics

Description

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

Usage

reverse_cut(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 reverse_cut to get factor levels ordered from high to low
table(reverse_cut(mtcars$mpg, breaks = c(Inf, 20, 15, -Inf)))

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