Well, what do you expect then? You're asking to access from 1:col-1 for
columns in cyy() which has only 900 columns but image() is 3x the width.
One obvious fix (for this specific problem, anyway) would be to run the
loop over
[row,col=size(cyy);
but whether that has any bearing on the problem you're trying to solve
is anybody's guess--only you can know what it is you're attempting to
accomplish here.
