optim, constrOptim: setting some parameters equal to each other
...one express the constraint I described above in terms of the ui, ci, and theta parameters?

Printing the null hypothesis
Dear R developers, Currently many (all?) test functions in R describe the alternative hypothesis, but not the the null hypothesis being tested.

I currently have a single PRI however we are getting a second PRI, and the provider (qwest) wants to know if our PBX supports GSAS (they say its a redundant d-channel technology but searching on google for GSAS reveals less than nothing). I've set something similar up before on a cisco 5350, where if one of the PRIs fails, all of the calls destined for either PRI will be routed down the one

a single nfs file system shared out twice with different permissions
I am trying to configure a system where I have two different NFS shares which point to the same directory. The idea is if you come in via one path, you will have read-only access and can''t delete any files, if you come in the 2nd path, then you will have read/write access. For example, create the read/write nfs share: zfs create tank/snapshots zfs set sharenfs=on tank/snapshots root
