Hello! I have created a bplot-figure using this code: *file <- "2dcali_red.ttt" ux<-as.matrix(read.table(file, dec = ","))
mode(ux)<-'numeric' vel<-ux[,1] ang<-ux[,2] x<-ux[,3] y<-ux[,4] dat<- data.frame(ang=ang, x=x,y=y) require(rms) ddist2 <- datadist(dat) options(datadist="ddist2") fitn <- lrm(ang ~ rcs(x,4) + rcs(y,4), data=dat) predi <- Predict(fitn, x, y) bplot(predi,lfun=wireframe, screen = list(z = -40, x = -80), drape=TRUE)* The file 2dcali_red.ttt consists of 4 columns can be found here : http://www.color-space.de/upload/dl/2dcali_red.ttt link The code gives me the bplot-figure, which looks like this: http://r.789695.n4.nabble.com/file/n4544050/Screen_shot_2012-04-10_at_12.04.24_AM.png Now I want to add some 3d data (x,y,z) to this plot (like scatterplot3d), but i don't know how. I also don't know how to extract the x,y,z mesh as coordinates from the bplot. Some help would be very appreciated.
