Predicción de valor máximo en superficie de respuesta, con paquete rsm
...quete
"rsm" para superficies de respuesta. Siguiendo este ejemplo todo va
bien, hasta que trato de obtener el valor máximo predicho para la
variable de respuesta en los valores de x1 y x2 estimados.

CR <- coded.data(ChemReact, x1 ~ (Time - 85)/5, x2 ~ (Temp - 175)/5)

How can I get the interpolated data?
Hello,everybody!
I am a beginner of R.
And I want to ask a question. If anybody would help me, thank you very much
ahead.
I want to plot something like a response surface, and I find the "rsm"
package.
Some commands are like this:
#code head
library(rsm)
CR = coded.data(ChemReact, x1 ~ Time, x2 ~ Temp)
CR.rsm = rsm(Yield ~ SO(x1,x2), data = CR)
summary(CR.rsm)
contour(CR.rsm,x1~x2)
#code end
What if I want the data interpolated, what should I do?
For example:
There is a data frame like:
xa1<-seq(86,88,len=21)
xa2<-seq(175,179,len=41)
z<- ... # referring site(xa1...
