[R] Plot a sphere
To plot the sphere in R I find the best scatterplot3d package as follows: library(scatterplot3d) a=seq(-pi,pi, length=100) x=c(rep(1, 100) %*% t(cos(a))) y=c(cos(a) %*% t(sin(a))) z=c(sin(a) %*% t(sin(a))) scatterplot3d(x, y, z, type=l) Best regards Branimir K.

[R] R-OpenOffice.org Calc
I have been very satisfied with R-Excel interface (DCOM). Few months ago I have changed my OS to Linux-Mandrake, and now I am using OpenOffice.org Calc as spreadsheet. I would like to know does exist some R-OpenOffice.org interface or how is possible to use R-functions in OpenOffice.org Calc? Thanks a lot! __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
