Hello I recently switched from apcupsd to NUT2.2.2 without any troubles. I tried to figure out how I can configure the self-test intervall. The command upsrw lists only the variables battery.charge.low battery.runtime.low ups.delay.shutdown ups.delay.start The command usbhid-ups -D and the listing under http://obsvermes.org/cgi-bin/nut/upsstats.cgi?host=apcsmart at localhost&treemode

This is not an R question, but a question on some combinatorial mathematics. Apologies for the OT if it is wildy inappropriate. The traditional C(n.k) method tells me how many combinations k I can make with n objects. However, suppose I want the number of combinations where an object cannot be used more than Q times where Q is a parameter that changes? For instance: combn(LETTERS[1:5], 3) shows the number...

Looks like the parsing for generic tunnels ( with protocol and port) in usr/share/shorewall/firewall in the 1.4.6_20030813 is not correct. The patch below fixes it for me.

I have a problem involving state space models with a multivariate observation equation. In other words: the kalman filtering routines as implemented in the package ts cannot be used since it treats the univariate case only. My question : does a multivariate kalman filtering procedure for R exist somewhere in the world? Where could I perhaps expect to find something like that? Many thanks M.

...ipt twice, once before a bunch of stuff, and once after, in order to perform a crude version of time measurement. However, the script sometimes (1 out of 20? 40?) will return with fewer digits in the output of the AGI, which means that when I do my subtraction, the numbers come out negative or wildy incorrect. I'm throwing 5 calls into the outgoing spool at once during these tests. What's going on here with AGI return values getting chopped? Sometimes the first column gets chopped, sometimes the second column gets chopped. Numbers can and do end in "0", so this is not a...
