Please give a _reproducible_ example on the current version of R (2.0.0).
It works fine for me using the example in ?ppr:
> rock.ppr <- ppr(log(perm) ~ area1 + peri1 + shape,
+ data = rock, nterms = 2, max.terms = 5,
optlevel=0)> rock.ppr
> rock.ppr <- ppr(log(perm) ~ area1 + peri1 + shape,
sm.method="gcvspline",
+ data = rock, nterms = 2, max.terms = 5, optlevel=0)
Neither of the above crashes, nor gave any error.
WinXP Pro with R-2.0.0.
