makeChrStrandData,ExpressionSet-method

makeChrStrandData,matrix-method

Given a data matrix with row names corresponding to the probe or gene IDs in
 an accompanying annotation package, returns a data structure that can
 be used with the <code>plotChrMap</code> function. Based on the Makesense
 method from the geneplotter package.

methods

The ChromHeatMap package can be used to plot genome-wide data (e.g. expression, CGH, SNP) along each strand of a given chromosome as a heat map. The generated heat map can be used to interactively identify probes and genes of interest.
