xtile {statar} | R Documentation |
Bin variable in groups (similar to Stata xtile)
Description
Bin variable in groups (similar to Stata xtile)
Usage
xtile(x, n = NULL, probs = NULL, cutpoints = NULL, wt = NULL)
Arguments
x |
A vector |
n |
A numeric specifying number of quantiles. Can be used instead of cutpoints |
probs |
A vector of probabilities that an be used instead of cutpoints. Quantiles are computed as the inverse of the empirical distribution function (type = 1) |
cutpoints |
Cutpoints to use when |
wt |
A variable specifying weight in case the option n_quantiles is specified. |
Value
An integer vector representing groups corresponding to cutpoints. Includes missing values when present in the original vector.
Examples
x <- c(NA, 1:10)
xtile(x, n = 3) # 3 groups based on terciles
xtile(x, probs = c(0.3, 0.7)) # 3 groups based on two quantiles
xtile(x, cutpoints = c(2, 3)) # 3 groups based on two cutpoints
