My guess is that your model is predicting a negative mean for some of your
data. Since this is not possible for a Gamma r.v. the deviance calculation
returns something non finite, which triggers the error message. This is
possible because you have used an identity link. Is it not possible to

Dear R-users,
Let me ask about the 'stack overflow' error which I got when I used
the function 'combinations' in gtools.
The following is what I did:
-
library(gtools)
options(expressions=1e5)
combinations(500, 3, 1:500)
# or combinations(400, 2, 1:400)
Error: protect(): stack overflow
These would more properly be called permutations of a multiset.
You can find code on the net by searching for generate permutations
multiset (though not in R AFAICS.)

The documentation for 'combinations' explicitly describes this problem:
Details:
Caution: The number of combinations and permutations increases
rapidly with 'n' and 'r'!.
To use values of 'n' above about 45, you will need to increase R's
recursion limit. See the
combn in package combinat does not use recursion, and so may be simpler
to use and may be able to do larger sets.

In principle R can handle this with enough memory. However,

Yes, 'combn' is much simpler to use than 'combinations'.
Although Greg's 'combinations' is useful as well, 'combn' didn't produce

'combn' works very well even in Windows.
Thanks again, David.

I don't think it is a bug. The problem is that poly(x, 2) depends on the

missing values is not a good idea in such cases, especially if the values
