Arguments

file

Character vector specifying the path of the file to be read in.

...

Optinal arguments, currently not used.

Details

With these methods the expression data and the assignment of the samples to groups can be read from ‘.cls’ (categorical class) and ‘.gct’ (gene cluster text) files, respectively. Details on the specific formats can be found at http://www.broadinstitute.org/cancer/software/gsea/wiki/index.php/Data_formats.

Please note that the readCls method reads only categorical class labels, not continuous ones.

Value

For a ‘.cls’ file, a factor containing the groups.

For a ‘.gct’ file, a matrix containing the expression intensities, with rows corresponding to genes and columns to samples.
