Arguments

ld.mat

A square matrix of LD coefficients

ld.type

A character value specifying what coefficients are used as input: either 'r' for correlation coefficients or 'd' for D/Dprime scores

color

A range of colors to be used for drawing. Default is heat.colors

title

Character string for the title of the plot
