Prostate2000Raw: Prostate Cancer 2000 Raw Spectra

Description

A data object of class msSet, consisting of 654 mass spectra (327 spectra in duplicate) from 2000 to 20000 Da, which were generated from patients with prostate cancer, benign prostatic hypertrophy, and normal controls. These spectra are already baseline corrected and normalized. Please see the references for more details.

Since the original package msProstate is orphaned at the end of 2012, the data are included in the ChemometricsWithR package so that the examples in the book are still executable. This manual page has been adapted to reflect this.
