dendrogram |
character string indicating whether to draw 'both' or none' |
sort |
sort rows and columns based on clustering |
margins |
spacing of plot |

additional arguments to heatmap.2 |
Plots image of correlation matrix using customized call to heatmap.2
Image of correlation matrix
# simulate simple matrix of 10 variables mat = matrix(rnorm(1000), ncol=10) # compute correlation matrix C = cor(mat) # plot correlations plotCorrMatrix( C ) # plot squared correlations plotCorrMatrix( C^2, dendrogram="none" )
