Re: [R] persp and trans3d for type="h" points

You are drawing the line to the center of the plot (which is 0 be design). What you actually want is to plot segments to the min(z) value. Example: Z <- matrix(1:9, 3) surf <- persp(1:3, 1:3, Z) points(trans3d(x=2, y=2, z=5, surf), col="red", pch=19) from <- trans3d(x=2, y=2, z=5, surf) to <- t

Re: [R] txtProgressBar and parallelized foreach

I think you do not understand how the parallelization works: Different iterations from your foreach() are run on different nodes, hence you change the progressbar on the node rather on the master in your loop. Uwe Ligges On 14.06.2011 12:23, Julian TszKin Chan wrote: Hi all, I can create a
