rsm.design
data.frame to an
rsm.factor, resulting
in an
rsm.design object, an object suitable for fitting a response
surface.
as.rsm.design(x, rsm.factors=seq(length(x)), logx = F)
data.frame, or something that can be converted to a
data.frame
by
as.data.frame.
x that designates the
vbariables that are to be converted to
rsm.factors. Other variables
are returned unchanged.
rsm.factor is evenly spaced on the log scale.
rsm.design object.
The functions
rsm.lm and
plot.rsm.design rely on the data having
attributes of the class
rsm.design. When the experiment is read from
an external file, via
read.table
for instance, a user can use
as.rsm.design to interface easily
to the response surface fitting functions of the S+DOX module.
If you wish to convert a
fac.design object to an
rsm.design, see
the function
convert.to.rsm.
my.df <- read.table("rsm.dat")
my.rsmdf <- as.rsm.design(my.df, c("temp", "pressure"))
