Hi, I have a question about exporting interactive 3D plots. I use the following code to plot a contour of a trivariate normal distribution: library(mvtnorm) library(rgl) library(misc3d) n=25 x=seq(-3,3,length=n) X=cbind(rep(x,each=n**2),rep(rep(x,each=n),n),rep(x,n**2)) p=array(dmvnorm(X,sigma=diag(3)*0.5+0.5),c(n,n,n)) contour3d(p,x,x,x,level=mean(p)) lim=c(-3,3)

Hi, Time for another of my "newbie" questions. Is it possible to build up a data.frame "row by row" as I go I'm going to be running a bunch of experiments (many in a loop) to test different things. I'm using AUC as my main performance measure. My thought was to add a row to a data.frame for each iteration and then have a nice summary report at the end. I found

It seems that an vector or other non elemental data type can not be assigned to an element in the data.frame. I'm wondering what is the walk around. > li=data.frame(a=c(0,1), b=c('x','y')) > li$b[[1]]= 'x' > li$b[[2]]<- c('y','z') Error in li$b[[2]] <- c("y", "z") : more elements supplied than there are to replace

Hi, is there a way to define, that a line drawn via abline() should only go from for example -2 to 1 on the x-axis (with something working similiar to xlim()) ? thanks for any help!
