3d plot
Hi,
I would like to have 3d plot, and I found that there is a command "scatterplot3d". x is V, y=sigmaV, and z=TSE (note: After some calculation, I update TSE). How could I do to have 3d plot I want?
V<-seq(1279,1280,,100)
sigmaV<-seq(0.28,0.29,,100)
TSE<-matrix(0, length(V),length(sigmaV))
ps: TSE[i,j] corresponds to V[i] and sigmaV[j].
Thanks,
Kate
