graph bugs using R on MAC
This is has been bugging me for a long time. Nobody around me seems to have this problem. I hope someone on the forum could help me. When I generate a R graph and want to bring the image into Word. I cannot copy and paste it like many of my classmates can do. The "Select" in Edit menu have all options grayed out. So what I ended up doing is to save it as pdf file and bring it

how to find unique pairs of variables?
I have two variables, both numerical. I would like to find the unique values of the pairs, in other words, unique coordinates if I were to plot them. I also need to know how many pairs there are, but I guess I can use length() if I can somehow isolate the unique pairs first? Thanks a lot! Bonnie Yuan

How do you further breakdown based on the values of both

import csv file into R, strange problem
Hi, I used read.csv(file name, header=T, sep=",") to bring in a csv file I saved in MS Excel. The strange thing is all the data ended up in one big column. The number of rows match with the number of observations, but all the variables got squeezed into one column. Also the first row where the header is, the variables names have a dot between them, replacing the comma that's in the

Tar Compression issue

Physical disks + Software Raid + lvm in domU
Hi, I''m trying to setup my box as described below: - The Dom0 exports two disks as physical devices to the DomU - DomU use the two devices to assemble a software raid device (/dev/md0) - On the /dev/md0 I create a lvm volume group and lvm volumes on it. Everything seems to work fine if the lvm volumes on the DomU are lightly used. Under heavy load the DomU freeze up immediately. The

Another printing problem...
I'm running samba 2.2.3a-6 under Debian (testing) and I am having a heck of a time getting Windows 2000 to print to my printer. I keep getting that "Access denied, unable to connect" message. At one point I had it so you could print test pages, but as soon as you tried to print from an application, it would break. However, that doesn't even work anymore. I've been reading

We (a small college with about 3000 active accounts) are currently in the process of moving from UW IMAP running on linux to dovecot running on a cluster of 3 or 4 new faster Linux machines.
