Hi, I've been trying to understand biplot. From getAnywhere(biplot.default), I could get the source code. However, there is one line that did make sense to me. It's the second line from the bottom.
arrow(0, 0, y[,1]*0.8, y[,2]*0.8, col = col[2],....) I don't understand why there is a multiplication by 0.8 for y. Thanks. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
