[Rd] largest acceptable lookup table in a package

[Robin Hankin]

Hi


One of my packages needs a look-up table of pre-calculated
numbers in the data directory.

I would like to have the matrix as large as possible.

What is the largest size matrix that would be an acceptable datafile in
an R package?



[
The table is a square, upper triangular matrix
consisting  of logs of Stirling numbers calculated by Maple.

As discussed on the List a few days ago (thanks again David!)
Stirling numbers  are computationally challenging;
one needs exact integer arithmetic for very large
integers  for their calculation (a 100x100 table requires  ~10^157)
