You _could_ indicate which package the image.plot function comes from.  
You _could_ include dput on a sufficient segment of `data1` to offer a  
reproducible test case. You _could_ indicate in what fashion the  
axis() call "didn't work". I used to look such matters up, add code  
and make guesses, but got tired of doing extra work that was really  
the responsibility of the questioner.
