R help - Jul 2012 - image function

Dear all,
   I have a question regarding changing the xlim and ylim in the function
image().
   For example, in the following code, how can I have a heatmap with
xlim=ylim=c(0, 100)
instead of (0,1).
   Thank you very much.

x <- matrix(rnorm(10000, 0,1), 100, 100)

image(x)

Hello,

image(1:100, 1:100, x)

Regards,
Pascal

Did you try this?
image(x, xlim=c(0, 100), ylim=c(0, 100))
