R: Deprecation notices.

xgboost-deprecated {xgboost} | R Documentation

## Deprecation notices.

### Description

At this time, some of the parameter names were changed in order to make the code style more uniform. The deprecated parameters would be removed in the next release.

### Details

To see all the current deprecated and new parameters, check the `xgboost:::depr_par_lut` table.

A deprecation warning is shown when any of the deprecated parameters is used in a call. An additional warning is shown when there was a partial match to a deprecated parameter (as R is able to partially match parameter names).
