omit points AND labels

[ripkrizbi]

Hi, would it be possible to add a parameter to omit drawing datapoints altogether? I have huge datasets with hundreds of thousands of points and I'm interested in displaying only the loading vectors and centroids. I know can use alpha=0, but even in this case, the plot takes ages to draw and the exported PDF still contains all the points, making it a huge file. A parameter that completely switches off plotting of datapoints (either as labels or as points) would be great. Thanks!

@ripkrizbi I recommend trying the experimental branch of ggbiplot. You should be able to do what you need by using layering.
