Hello! I'm looking for an easy way to filter data frames. Some rows in my data frame needs to be left out, for instance, rows with invalid data. Right now, if I want to pair two columns of this data frame, I have to do this: > pairs(as.data.frame(list(tstart=df$tstart[valid],tend=df$tend.sdr[valid]))) or this: >

How do people go about synchronizing multiple workspaces on different workstations? I tend to wind up with projects spread around the various machines I work on. I find that placing the directories on a server and reading them remotely tends to slow things down. thanks, Eric -- Eric Turkheimer, PhD Department of Psychology University of Virginia PO Box 400400 Charlottesville, VA 22904-4400

...nity. curve((1-pnorm(x))/dnorm(x),from=0, to=9) >From the plot we see that for x between 8.0 and 8.3 the function is fluctuating. As far as I understand, this is due to the function pnorm() not being sufficiently accurate in the tails. I am using pnorm() in a way that has probably not been intended. So I guess this should not be considered a bug (??) The function can also be written as 1/lambda(x) where lambda(x) is the hazard rate for the normal distribution. Is there a way to calculate lambda(x) without using pnorm() ? Any help would be appreciated. Cheers Ole Christensen -- Ole F....

The wiki says: > Each mailbox has its own separate index files. **If the index files are disabled**, the same structures are still kept in the memory, except cache file is disabled completely (because the client probably won't fetch the same data twice within a connection). [1] I tend to grep my maildirs quite often, and use the output to cp emails to other folders, so it's annoying

-----Original Message----- From: Brian Mathis The difference is that CentOS is a general-purpose OS that can be used for many things, and has a much bigger installed base. That makes it more of a target and would likely be included in scanning tools. A custom OS running on a PBX might also have vulnerabilities, but it's also probably not a big target because of the diversity of systems

Hello, I have a small statistics question, and as I'm quite new to statistics and R, I'm not sure if I'm doing things correctly. I am looking at two quantitative variables (x,y) that are correlated. When I divide the data set according to a categorical variable z, then x and y are more poorly correlated when z = A than when z = B (see attached figure). In fact x and y are two

Probably not. If there is, it would probably favor

Just out of curiosity (and I hope that my question does not confuse those who intuitively understood the par(new=TRUE) statement right in the beginning): I would like to know whether beginners (learning R) had the same difficulty as I had: Intuitively I thought that par(new=TRUE) would draw a new plot (and not into an already existing plot) and that par(new=FALSE) would not draw a new plot

hi all, i use sortables in a project, and it seems to have the following issue in IE6: while and after dragging the background pictures vanish... a simplified demo can be found here: http://files.caillou.ch/script.aculo.us/ i searched in the group, but couldn''t seem to find a solution. does anyone have a suggestion? greetz ... caillou

Folks, After looking at git / svn logs for a long time today, I realised that the commit messages could be a bit more helpful for that purpose (logs). The kernel has a good policy on commit messages, and I think we could use some of that, at least as a strong guideline, not as a hard rule. The idea, AFAIK, is to have a title with 50 chars, separated by an empty line and an infinite number of

My guess would be that people don't tend to run with -ffast-math (it's got a reputation for breaking code, even ignoring this particular issue). Without that, from what I can see the issue

Anyone made some performance comparison between XFS and ZFS with ZIL on SSD, in gluster environment ? I've tried to compare both on another SDS (LizardFS) and I haven't seen any tangible performance improvement. Is gluster different ?
