understanding and resolving seg faults
Dear r-devel,
I am mutating rpart to do calculations on trees.
I am trying to extract information from the tree.
However, I got a seg. fault.
This is the offending line in "rpmatrix.c":
deltaI[0][0] = spl->improve;
(Commenting it out cures the seg fault)
I would like some advice on how to debug this. I have allocated memory
with calloc and deltaI[0][0] should be OK, but apparently not.
thanks for your help,
For those that don't have structure of rpart drilled into their brai...
