prostate: Averaged prostate data from package msProstate.

Description

Prostate data, originally from package msProstate, where the three replicates have been averaged. Vector prostate.type is a factor, describing the type of sample: a control, a benign prostate enlargement or tumourous sample. Matrix prostate contains 327 rows (samples) and 10523 variables. Since package msProstate is orphaned at the end of 2012, the original data are also included here.

Usage
