Principle components analysis on a large dataset
Dear Sirs:
Please pardon me I am very new to R. I have been using MATLAB.
I was wondering if R would allow me to do principal components analysis on a
very large

Specifically, our dataset has 68800 variables and around 6000 observations.
Matlab gives "out of memory" errors. I have tried also doing princomp in
pieces, but this does not seem to quite work for our approach.

I realize GNU screen solves (iii), although I am interested in a slightly different purpose (nxssh vs openssh).
However, I am

Update on "non-dying" nx connections over unreliable network
Dear Sirs & Madams:
Thank you so much for your help. To remind, my situation is a wireless connection that is unreliable, where:
(a) upon disconnect, !M's nxclient does not recognize connection death
(b) after I manually kill nxssh and reconnect, reconnection takes some time.
My idea:
intercept myself in between NX client and server - detect connection drop, and reconnect. This is

ServerAliveInterval exit code?
Dear Sirs:
Thank you so much for your help. I have now created both the client and server for resumable nx sessions using the ServerAliveInterval option to disconnect after several seconds of server inaccessibility.
I am now working on an nxssh "substitute", which at this point seems fairly straightforward.
However, when I spawn ssh, I need to know whether:
(a) it exited because of

prototype of simple NX client with auto-resuming ssh session
Dear All:

Summary, especially for openssh list (to test/reproduce):
THANK YOU for all your help.
Please extract into /home/username/nx on both host and client. cp ssh to a file named mxssh in that directory. Run
(with an _n_ below)
Start server on the remote host by typing ./server &
Now do:
./nxssh hostname
If you killall client on the remote end, it reconnects "seamlessly"
