winsorize: Winsorize a numeric vector In statar: Tools Inspired by 'Stata' to Manipulate Tabular Data

Description

Winsorize a numeric vector

Usage

 ```1 2 3 4 5``` ```winsorize(x, probs = NULL, cutpoints = NULL, replace = c(cutpoints[1], cutpoints[2]), verbose = TRUE) winsorise(x, probs = NULL, cutpoints = NULL, replace = c(cutpoints[1], cutpoints[2]), verbose = TRUE) ```

Arguments

 `x` A vector of values `probs` A vector of probabilities that can be used instead of cutpoints. Quantiles are computed as the inverse of the empirical distribution function (type = 1) `cutpoints` Cutpoints under and above which are defined outliers. Default is (median - five times interquartile range, median + five times interquartile range). Compared to bottom and top percentile, this takes into account the whole distribution of the vector. `replace` Values by which outliers are replaced. Default to cutpoints. A frequent alternative is NA. `verbose` Boolean. Should the percentage of replaced values printed?

Examples

 ```1 2 3 4 5 6``` ``` v <- c(1:4, 99) winsorize(v) winsorize(v, replace = NA) winsorize(v, probs = c(0.01, 0.99)) winsorize(v, cutpoints = c(1, 50)) ```
