[R] Error in "color2D.matplot" : "Error in plot.new() : figure margins too large"

[shahab]

Hi,

I am using color2D.matplot (...) function of "plotrix" package. I used
a matrix of size  around 20*20
However, apparently it failed to visualize the matrix and gave the
following exception, which I don't have any idea about possible source
of this error.

 "Error in plot.new() : figure margins too large"

It would be appreciated if someone points me to the right origin of this error.

best,
