contour.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.
contour.default.
This function is a method for the generic function for class rsm.lm. It can be invoked by calling for an object x of the appropriate class, or directly by calling regardless of the class of the object.
ab.rsm <- rsm.lm(abrsm.df)
contour(ab.rsm)
sda.od.rsm <- rsm.lm(sda.df)
