Anova tables for fitted trend surface objects
DESCRIPTION: Compute analysis of variance tables for one or more
fitted trend surface model objects; where
anova.trls
is
called with multiple objects, it passes on the arguments to
anovalist.trls
.
USAGE:
anova.trls(object, ...)
anovalist.trls(object, ...)
summary.trls(object, digits = max(3, .Options$digits - 3), ...)
REQUIRED ARGUMENTS:
object
A fitted trend surface model object from
surf.ls
OPTIONAL ARGUMENTS:
digits
number of significant figures used in printing.
...
Further objects of the same kind
VALUE:
anova.trls
and
anovalist.trls
return objects corresponding
to their printed tabular output.

EXAMPLES:
topo0 <- surf.ls(0, topo)
topo1 <- surf.ls(1, topo)
topo2 <- surf.ls(2, topo)
topo3 <- surf.ls(3, topo)
topo4 <- surf.ls(4, topo)
anova(topo0, topo1, topo2, topo3, topo4)
summary(topo4)
