| ColorMatrix {greenbrown} | R Documentation |
This function creates a square matrix with two diagonal crossing color ramps. It can be used to plot contingency maps of two classifications.
ColorMatrix(dim = 3, ul = "burlywood4", lr = "darkgreen", ll = "khaki1",
ur = "royalblue1", ctr = "gray87")
dim |
number of rows and number of columns of the matrix (only square matrix are possible, i.e. number of rows = number columns) |
ul |
starting color in the upper left corner of the matrix |
lr |
ending color in the lower right corner of the matrix |
ll |
starting color in the lower left corner of the matrix |
ur |
ending color in the upper right corner of the matrix |
ctr |
color in the center of the matrix |
The function returns a square matrix of color names.
