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 434-982-4732 434-982-4766 (FAX) [[alternative HTML version deleted]]

...ported in that mode, so all bets are off. Zero is a perfectly reasonable result. The result of this is that we return 0 only under -ffast-math. In all other cases, the sqrt call will remain and we will return NaN. So that seems like a bothersome discrepancy given that the Posix standard wording tends to favor NaN (though an implementation-defined value is allowable, regardless of -ffast-math). As mentioned earlier, a number of other compilers also generate NaN with -ffast-math or its equivalent. I believe this is done to comply with the Posix wording. Regardless of feelings about playing ben...

Dear R people The function below should be decreasing, convex, and tend to zero when x tends to infinity. 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...

...p the caching in memory. I can find `mailbox_list_index = no` in /etc/dovecot/conf.d/10-mail.conf but this seems to be enabled by default, and it makes no difference when I enable it explicitly - deleted dovecot.index.cache are recreated when Dovecot is restarted. The setting `mbox_min_index_size` tends to suggests it's only for mbox files, not maildirs? Thanks in advance for any help you can offer, Stroller. [1] https://wiki.dovecot.org/IndexFiles

-----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

We at Facebook have a mix, but XFS is (I think) the most common. Whatever the developers use tends to become "the way local filesystems work" and code is written based on that profile, so even without intention that tends to get a bit of a boost. To the extent that ZFS makes different tradeoffs - e.g. using lots more memory, very different disk access patterns - it's probably goin...

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

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 ?
