I'm using 2.11.1 under the 32-bit Windows XP. I've also tested the codes under a 64-bit Ubuntu and the same problem occurred. By the way, right before Rgui shuts down, the \ pop-up window suggests it's a runtime error in C++. Here are the codes that cause the crash, library(mlbench) data(BostonHousing2) BH = BostonHousing2[,-c(1:5)] dat1 = BH[1:200,] dat2 = BH[201:400,] mod = ppr(log(cmedv)~., data=dat1, optlevel=0, nterms=2, max.terms=5) pred = predict(mod, newdata=dat2) Thks.

On 32-bit Ubuntu, clean session (--vanilla), it seems to work the first time and crash the second:
