Correlation Heatmaps
Cluster a correlation matrix and return the sorted matrix for plotting...
Draw Correlation Heatmaps
Automatically split clusters based on noise level and hierarchy
Draw correlation maps from large datasets.
Helper function to calculate the correlation matrix.
Create correlation heatmaps from a numeric matrix. Ensembl Gene ID row names can be converted to Gene Symbols using, e.g., BioMart. Optionally, data can be clustered and filtered by correlation, tree cutting and/or number of missing values. Genes of interest can be highlighted in the plot and correlation significance be indicated by asterisks encoding corresponding P-Values. Plot dimensions and label measures are adjusted automatically by default. The plot features rely on the heatmap.n2() function in the 'heatmapFlex' package.
