surface.rsm.lm(rsm.object, vary, granularity=50, ...)
rsm.lm
.
rsm.object
, that
determines which two factors are varied on the x and y axes while the
remaining factors are held constant. The components corresponding
to the factors to be varied are assigned the value
"v"
, while
the remaining components are assigned either an explicit numeric
value or the value
"c"
to indicate that the factor is to be held
constant at its center point. (If a variable is omitted from
the list,
"c"
is assumed.) By default, the first two factors
in
rsm.object
are varied.
