Only plotting upper triangular half of the cij matrix using plot.dccm possible?

[Former user]

Does plot.dccm support plotting only upper triangular matrix from dccm output or plotting different cij values in the upper and lower triangle of the plot from two different systems, etc.?

[Lars Skjærven]

I think you will have to manipulate the matrix prior to passing to plot.dccm. e.g:

ca[upper.tri(ca)] = cb[upper.tri(cb)]

# upper triag empty
ca[upper.tri(ca)] = NA

(where ca and cb are two DCCM's of same dimensions)
