Hello all,

I have gridded data which I loaded using the readAsciiGrid function.

?> x <- read.AsciiGrid("data.txt, plot.image=TRUE).
?> image(x)

This works OK but how do I:

1. know what values are assigned to which color/shade

2. change the color template e.g. rainbow

3. insert a color bar?

Thanks.

Muhammad
