[R] Variance Inflation factor

[Hui Du]

Thanks, all. I will upgrade my R in linux but I suspect the root cause is some set up problem although I don't know how to trace it yet. I am not that familiar with R in Linux. If somebody could give me a clue how to diagnose this kind of problem, that will be great.

You're rather out of date with your version of R -- if you want to use
the CRAN binaries provided by install.packages(), you usually have to
be at most one minor rev behind.

Try install.packages("car", type = "source")

But even better -- update to a poppin-fresh R 2.15.1: you get
parallelization, a byte-code-compiler, and all sorts of other goodies.

Best,
Michael
