getGroups {cNORM} | R Documentation

## Determine groups and group means

### Description

Helps to split the continuous explanatory variable into groups and assigns the group mean. The groups can be split either into groups of equal size (default) or equal number of observations.

### Usage

    getGroups(x, n = NULL, equidistant = FALSE)

### Arguments

`x` | The continuous variable to be split
`n` | The number of groups; if NULL then the function determines a number of groups with usually 100 cases or 3 <= n <= 20.
`equidistant` | If set to TRUE, builds equidistant interval, otherwise (default) with equal number of observations

### Value

vector with group means for each observation

### Examples

    x <- rnorm(1000, m = 50, sd = 10)
    m <- getGroups(x, n = 10)
