Hi, I'm using the latest version of 64-bit R for Windows: R x64 2.12.1
I'm using it because I currently need to do hierarchical clustering on a
very large object (too big for MATLAB, which I normally use).
When I try to cluster my distance matrix d (obtained using dist on my design
matrix):
hc<- hclust(d, method = 'average')
I get an errror:
Error in hclust(d, method = "average") :
cannot allocate memory block of size 3.8 Gb
However, the memory limits appear to be 16GB:
memory.limit()
[1] 16378
Does anyone know why R cannot allocate a memory block of size 3.8 GB, even
though this is well within its memory limits??
If the available space got too fragmented, there is not single 3.8 block
of memory available any more....

Any help would be greatly appreciated!
Thanks alot,
