I'm using 1.6.2 on a win 2k box. (I know I'm due for an upgrade.) I've used brute force to label a series of vectors, and I'm wondering if there's a better way to do this. I wanted to create a biplot of the 2nd 3rd PCs, and did this: test - edit(loadings(cv.prc.spr)) test.1 - test[,1] test.2 -

[R] color coding a legend

I'm using R 1.6.2 on a Windows 2000 machine. I've plotted the results of an MDS run labeled by a numerical ID, and color coded by a group code: plot(cv.mds.spr$points, type=n, main=Non-Metric Multidimensional Scaling of SprRun CV Watersheds) text(cv.mds.spr$points, labels =

[R] Conditioned file Import?

I'm using R 1.6.2 on Windows 2000. I have two similar sets of files in two different directories. One contains species presence data and environmental measurements; the other contains species absence data and environmental measurements for the same variables as the presence data. The absence
