xMLrename {Pi} | R Documentation

## Function to rename predictors used in machine learning

### Description

`xMLrename` is supposed to rename predictors used in machine learning. It returns an object of class "sTarget".

### Usage

    xMLrename(sTarget, old_names, new_names)

### Arguments

`sTarget` | an object of class "sTarget"
`old_names` | a vector for the original names of predictors to be renamed
`new_names` | a vector for the new names

### Value

an object of class "sTarget"

### Note

none

### See Also

`xMLrandomforest`
