\name{CAFE-package} \alias{CAFE-package} \alias{CAFE} \docType{package} \title{ Chromosomal Aberrations Finder in Expression data } \description{ CAFE attempts to find chromosomal aberrations in microarray expression (mRNA) data. It contains several plotting functions to aid in visualizing these aberrations. It generally recapitulates the workflow described by Mayshar et al (see references), and implements several algorithms described by Friedrich et al (see references). } \details{ \tabular{ll}{ Package: \tab CAFE\cr Type: \tab Package\cr Version: \tab 0.6.9.5 \cr Date: \tab 2013-05-16\cr License: \tab GPLv3\cr } } \author{ Sander Bollen } \references{ Friedrich, F., Kempe, a, Liebscher, V., & Winkler, G.
