R for Mac OS X: new version on 3rd Oct

Universal R 2.13.2 released on 2011/10/03

This binary distribution of R and the GUI supports PowerPC (32-bit) and Intel (32-bit and 64-bit) based Macs on Mac OS X 10.5 (Leopard), 10.6 (Snow Leopard) and 10.7 (Lion). It is possibly the last distribution supporting Mac OS X 10.5 (Leopard) and PowerPC architecture. This update is highly recommended to R.app GUI users on Mac OS X 10.7 (Lion) since it works around several issues in Lion.
