expressionPlot {clusterCons}

Generate a profile plot for the data partitioned by cluster membership.

Description

This function uses the lattice function xyplot to generate a profile plot of the data values grouped by cluster in a multi-panel plot. The function takes as input the original data.frame() and a valid "consmatrix" class object (see consmatrix-class) by which to segregate the data.

Usage

expressionPlot(x,cm);

Arguments

x

the original data.frame() object used in the clustering.

cm

a valid "consmatrix" class object generated by the cluscomp function.

Value

No return value, called for side effects

Examples

#load up the data set
data(sim_profile);

#load up an example cluscomp result with this data
data('testcmr');

#plot the expression profiles
expressionPlot(sim_profile,testcmr$e1_kmeans_k4);
