hello,
I have a problem when call dist() of package mva on a large data
set. The following error message are obtained when I use dist()
on m, a two dimensional data set with the size 100,000. It seems
that the length of vector out of bound, since when I compute
dist on small data set(10,000), it works well. but for large
data set, it exit with the message "negative length vector are
not allowed" .
With 100,000 points there are 50 billion pairwise distances, which would
take at least 400 Gb of memory. It probably wouldn't even fit on your
disk, let alone in memory.
