slm.fit(x, y, cov.family, initial, spatial.arglist, ...)This function is included to be consistent with the
lm routines.
It performs a few assignments for the
slm routine,
but these are not critical.
See function
slm for additional information.
For most purposes, you would be better off calling the lower-level
function directly unless you want to write code that takes the
method argument.
