Hi,
Without knowing any details of what you did, the general procedure is:
Use your fitted Random Forest or SVM model to predict the class for
each pixel in your region of interest - the predict() function.
Use standard spatial data methods to aggregate the resulting spatial
data, or even standard non-spatial methods, since you know the pixel
size - perhaps aggregate() or even table().
