Re: [R] seg fault with randomForest ( ... , xtest )

Hi Clayton, Using formula like that, IMHO, is a genuinely bad idea. You subset Y on the LHS of the formula, but what about the RHS? Also, I've never tried to use xtest via the formula interface, and that is never the intended usage. I'll look into more checking in the code to prevent such

[R] seg fault with randomForest ( ... , xtest )

Dear R-help, what are the limits on xtest? NOT_A.rf - randomForest (log10(Y[!A] ) ~ . , data = notA_desc , proximity=T ,xtest = A_desc) *** caught segfault *** address 0x9cdd000, cause 'memory not mapped' Segmentation fault I don't think that the matrix are large: notA_desc is 651 obs
