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)
