R help - Apr 2010 - Creating artificial environmental landscape with spatial autocorrelation

Dear all:

Does anyone have any suggestions on how to make a spatially explicit landscape
with spatial autocorrelation in R? In other words, a landscape where all cells
have a spatial reference, and the environment values that are closer in space
are more similar (positive spatial autocorrelation).

Thank you,
Laura
