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,xa2) from the contour plotted above or xa1 xa2 z 86 175 ??? 86.1 175 ??? ... ... ... 86.7 177.3 ??? ... .... ... 88 179 ??? or something alike. How could I get the z value(???) from the CR.rsm or the plotted contour? -- View this message in context: http://www.nabble.com/How-can-I-get-the-interpolated-data--tp21114660p21114660.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
