Breast Cancer Gene Expression
Gene expressions for 7129 genes in 49 breast cancer samples and the status of lymph node involvement.
data("Westbc")An list with two elements to be converted to class ExpressionSet (see package Biobase).
A full description of the data can be found in West et al. (2001) and an application of boosted linear models is given by Buehlmann (2006).
