Dear R users -- I have a simple question that I cannot find the answers in the archive email: how to plot a multivariate function if I know the coefficients already? For instance, if I like to plot a 3D fig of Pi against X and Y with the function Pi = a0 + a1X + a2Y, where a0, a1 & a2 are known. Can "curve" do this? So far, I have only seen univariate case.
Thank you. Yihsu Chen ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
