Hi all!
My question is how to colour pixels by z value in persp plot in raster package.
Here is an example:
x <- seq(-1.95, 1.95, length = 30)
y <- seq(-1.95, 1.95, length = 35)
z <- outer(x, y, function(a,b) a*b^2)
r1 <- raster(nrows=35, ncols=30, xmn=0, xmx=30, ymn = 0, ymx = 35)
r1[] <- c(z)
persp(r1)
There already exist some function to produce persp plot for anothe classes, but
I have no idea how deal with RasterLayer object.
Thanks all!
