## Compare current R version with a specified one

### Description

Determine if R is older (return -1), or not (return 0 if equal, or 1 if newer) than a given version number.

### Usage

    compareRVersion(version)

### Arguments

`version` | a string defining the version to compare to, like '2.0.0' or '1.9.1'.

### Value

-1 if R is older, 0 if equal, 1 if newer. Take care: if you specify version as "2.11", and R is version "2.11.0", then the function will return 1 (newer)!
