Dear all I would like to plot the contents of a matrix as an Image. I found this code here http://www.phaget4.org/R/image_matrix.html but this is not only what I want. Instead of having inside every cell the color of the cell it would be nice to have also the arithmetic value over the background color. Having only the color sometimes does not make it clear to understand what is the value each cell has .. so I was thinking to combine colors and text inside every cell. I would like to thank you in advance for your help Best Regards Alex.

Thanks a lot.

Hello again,
actually I am trying to store many files to hard disk and thus I want to
1.create new plot
2.save it
3. close it
I have successfuly completed 1 and 2 but when I try to close it
color2D.matplot(tespa,redrange=c(0,1),greenrange=c(0,.5),bluerange=c(0,.5),xlab="x",ylab="y",main=sprintf("TestTitlos
%d",2),show.legend=TRUE,show.values=TRUE)
dev.off(dev.cur())
it doesnot.
it seems for me that it takes some time until color2D.matplot is printed out and
thus when dev.off(dev.cur()) is issued has nothing to close.
What should I try to do for that?
Best Regards
Alex
