In low-decarie/ggpca: Creates ggplot biplot methods for pca objects

ggpca

ggplot plotting of pca analysis

install.packages("devtools")
require(devtools)

devtools:::install_github("ggpca","low-decarie")

Currently available * ggbiplot generic S3 function

• ggbiplot.princomp biplot for prcomp
• ggbiplot.prcomp biplot for princomp
• ggbiplot.default biplot used internaly

This 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
