plot.assoc {plot.matrix}

plot.assoc

Description

Visualizes a association matrix with a colored or gray heatmap. As a rule of thumb the breaks are determined by the effect sizes given by Cohen (c(-1, -0.4, -0.2, -0.05, 0, +0.05, +0.2, +0.4, +1). You may need to modify mar with the par command from its default c(5.1,4.1,4.1,2.1). See

• vignette('plot.matrix') for detailed examples, and

• plot.matrix for further parameters.
