exploreOnlybic {BcDiag}

R Documentation

The exploreOnlybic function

Description

Provides exploratory plots only for biclustering results.

Usage

exploreOnlybic(dset, bres, pfor= "all", gby= "genes", mname="biclust",bnum=1, 
fabia.thresZ=0.5,fabia.thresL=NULL)

Arguments

dset	data matrix.
bres	biclustering result.
gby	group bicluster; 'genes' or 'conditions'.
pfor	fit a plot for 'mean', 'median', 'variance', 'mad', 'all', or 'quant' (quantile).
mname	method name; 'biclust', 'isa2', 'fabia' or 'bicare'.
bnum	existing biclusters; '1','2'...
fabia.thresZ	Bicluster threshold for mname="fabia". Threshold for sample belonging to bicluster; default 0.5.
fabia.thresL	Bicluster threshold for mname="fabia". Threshold for loading belonging to bicluster (if not given it is estimated).

Details

The exploreOnlybic function has similar function with exploreBic. The only difference is that it provides exploratory plots only for biclustered data.

Value

Summary plot will display only for biclustered data.

Note that the "biclust" option for mname will also accept results from the packages iBBiG and rqubic.
