Well, what do you expect then? You're asking to access from 1:col1 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 guessonly you can know what it is you're attempting to accomplish here.
