[R] cv.lars() function in LARS package

[minxolee]

I am trying to get familiar with the lars package and find out by repeating
the cv.lars() function, I am not getting the same result consistently. Could
someone help on that? Here is a simple reproducible example.

> library(lars)
> data(diabetes)
> attach(diabetes)
> cv.lars(x,y,K=2)
> cv.lars(x,y,K=2)

The last two runs of cv.lars give out different cross-validation plots.

Thanks,
minxolee
