R: Empirical Percentile Transformation

percentize {heatmaply} | R Documentation

## Empirical Percentile Transformation

### Description

An Empirical Percentile Transformation (percentize) is similar to taking the rank of a variable. The difference is that it is simpler to compare and interpret the transformed variables.

This is helpful for comparing several variables in a heatmap (e.g.: heatmaply).

### Usage

    percentize(x, ...)

### Arguments

`x` | a vector or a data.frame.
`...` | Currently ignored.

### Value

A vector (or data.frame) after ecdf was used on that vector. If x is a data.frame then only the numeric variables are transformed.

### See Also

normalize

### Examples

    ## Not run:
    x <- mtcars
    x <- data.frame(x)
    x$am <- factor(x$am)
    x$vs <- factor(x$vs)
    heatmaply(percentize(x))

    x <- data.frame(a = 1:10, b = 11:20)
    x[4:6, 1:2] <- NA
    percentize(x)
    percentize(x[,1])
