Computing very large distance matrix

If that's 131072 points, not 132 points, the memory needed to store that is:
131072^2 * 8 / 1024^3
[1] 128

That's in gigabytes.  When you have a Windows machine that has at least that
much memory, you can try to do that.  Before then, try something else.

Hello All,

I have a 131072x132 matrix for which I need to compute a 
regular euclidean distance matrix, which I then need to 
transform and run agnes() on this transformed matrix. I am 
having trouble computing the distance matrix as it is fairly 
large and I am sure I have gone over the max. 

The specific error I am getting is:
Error in vector("double", length) : negative length vectors 
are not allowed

I have increased the memory limit to the maximum capacity of 
my hard drive (which is around 20gb), with no success. 

I am running the RGUI on Windows XP with 512 mb of RAM.

Would anyone have any suggestions as to how I can overcome 
this problem? I would be most grateful for any help.

Thanks,
Arnav
