Draw a heatmap for the genes of a pathway
Description
Draw a heatmap for the genes of a certain pathway based on the expression profile user specified.
Usage
drawAHeatMap(Result, Name, PCExpr, Labels)
Arguments
Result |
A lncPath object come from the lncPath function. |
Name |
A string, the name of the pathway to be plot. |
PCExpr |
A data frame, the expression profile to be plotted. |
Labels |
A vector of 0 and 1, 0 indicates control and 1 indicates case. |
Details
Draw a heatmap of the genes of a pathway based on the expression profile. The rows of heatmap are genes ranked by their weights and the columns of heatmap are samples ordered the same as the expression profile.
