biplot used internalyThis is an exercise in creating a package and is obviously a work in progress. This may not be the proper approach to producing a biplot from a PCA analysis. Feedback is appreciated. Plans: - [ ] allow control of number of predictive variables plotted - [ ] auto select scale - [ ] improve documentation - [ ] add basic plotting method for pca objects (equivalent to plot(princomp(x)) - [ ] create methods for other classes - [ ] PCA in FactoMineR - [ ] dudi.pca in ade4 - [ ] acp in amap
