[R] Netlogit and large networks

[Tom Brökel]

Dear R-users,

I'm trying to use the netlogit QAP procedure in the SNA package for an adjacency matrix of 4500*4500 (undirected). However, my computer is not able to handle this task due to a lack of memory (2GB of RAM). The error message is something like "... cannot allocated vector of size... MB". Is there any possibility to reduce the RAM usage of that procedure? Can I store the data differently than in an Array(), which might use too much RAM?
Thanks in advance for your help.

Tom
