someone know if it is possible to use R to calculate distance by sea
between two geographic coordinates? I have many points in the sea and I

All,
Got a tricky situation and unfortunately because it's a big file I can't
exactly provide an example, so I'll describe this as best I can for
everyone.
I have a distance matrix that we are using for a modeling calculation in
space for multiple days. Since the matrix is never going to change
How are you writing it out now? Are you using 'save' which will compress
the file? What are the range of numbers in the matrix? Can you scale them
to integers (what is the range of the numbers) which might save some space?
You did not provide enough information to make a definitive solution.
Hello again Thanoon,
Once again, you should send these request not to me but to the r-help
list. You are far more likely to get help from the greater R community
than just me. Furthermore, it is not entirely clear where your error is.
It is courteous to provide only the code that is run up to

At the moment I'm using write.table. I tried using write.matrix from the
MASS package, but that failed. Integers are not appropriate here because
we are working with fractions of miles for some locations and that needs to
be retained. The range is from 0 to about 3.5 (it's a little less
The real question is how much memory does the machine that you are working
on have. The 32000x32000 matrix will take up ~8GB of physical memory, so
how much memory will the rest of your objects take up. Are any of them
going to be copies of the distance matrix, or is it always going to be
If it is possible at all (and I suspect it is) then it should be possible in R.
However, your question is lazy... you should not be asking about black boxes
that magically solve your problem, but rather do a search for algorithms that
accomplish your goals (wouldn't you want to know if someone
Jim,
There are not going to be additional copies of the distance matrix. The
distance matrix is what is needed for a geographically weighted regression,
so I can estimate the results from that to be a SpatialPointsDataFrame at
roughly 3 rows by 7 columns. Much smaller size than the distance
Package geosphere has functions to compute the great circle distance between
any two points given the latitude and longitude. It does not care if they are

Adrienne,
I have a crew just starting work on this problem this week, but I
think in your case the best solution is more memory. R stores the
distance matrix as a vector with (n^2-n)/2 entries. It's perfectly
dense and immune to sparse matrix compaction. It would be quite
possible to

R_ENVIRON should not point to your .Rpofile, use R_PROFILE_USER for

It is a nuisance that bitwShiftL and bitwShitR don't just shift (and

You could use doubles and multiply (*) and divide (%/%) by 2^n instead

If you have zeros in the supplied sample weights, the display in the
summary() function will look like this. Nothing is actually wrong with
the calculations, though.
If the zero weights are because of restriction to a subpopulation, you
will get better-looking summaries if you put the whole
