Greetings all, I'm porting an algorithm from MATLAB to R, and noticed some minor discrepancies in small decimal values using rowSums and colSums which are exacerbated after heavy iteration and log space transformation. This was rather perplexing as both programs claimed and appeared to use the IEEE 754 standard for floating point arithmetic (confirmed with manual basic operations). After some tracing and testing, I've managed to isolated a minimal worki...

Hi all, Are there any plans for better documentation for the new StoryRunner feature? I tried to use it today (with Rails), and had a hard time getting my head around whether I was doing it "right" and exactly what things are appropriate to test at that level (this might be exacerbated by the fact that I''ve never really used integration testing that much). A full example of testing a Rails controller would be extremely useful to me. Thanks, Jon -- Jonathan Leighton, Web Developer http://jonathanleighton.com/

dear R wizards---more ignorance on my part, exacerbated by too few examples in the function documentations. > d <- data.frame( id=rep(1:3,3), x=rnorm(9), y=rnorm(9)) Question 1: how do I work with the output of "by"? for example, > b <- by( d, d$id, function(x) coef(lm( y ~ x, data=x ) )) > b d$id: 1 (Intercept) x...

...ent factors predict the 37 items in a psychological battery. However, the display on the screen has very large font size for the coefficients of the relationship between the 11 factors and the 37 items, so the numbers overlap and are therefore illegible. When I output this to a pdf the problem is exacerbated even further (see attachments). I tried to use cex=0.8 and cex=0.4 in the pdf argument but it made no difference - what can I do? The code I used is: fa.diagram(fa.11factors.rawdata) # Start PDF device driver to save output to fa_diagram.pdf pdf(file="I:\\ZAPi\\Tables-of-R-output\\fa_diagram....

...Real) had frequency response problems, AAC had background noise, and WMA lacked impulse response. So I don't think I should be concerned about my hearing... At 128kbps, however, most of the frequency response problems were gone -- except this time, I picked Ogg as the worst, based on an overly exacerbated treble. Others were still noisy and lacked impulse detail, but Ogg/Vorbis was the one I decided first was definitely not close to the original. Listening to it again, I can confirm the difference I heard, although maybe I wouldn't put it in last place this time. The passage I based the Ogg/Vor...

...startt<- strptime((paste(data2$V4, data2$V5)), "%d/%m/%Y %H:%M:%S") This executes without any warnings, but returns a full column of NA values. It would be great to fix this, and then to know how to correctly add column V6 as seconds to the resulting column. The problem is further exacerbated by an error with dput() with this data. It's a large dataset of over 9000 rows, and when I call: dput(head(data2,50)) It returns dput(), but for all the data (i.e. not the first 50 rows). This of course does not fit on the workstation screen and therefore I cannot find out what class it has a...

Do you often find yourself doing this: active = double(''active'') active.should_receive(:first) users = double(''users'', active: active) account.should_receive(:users).and_return(users) for this: account.users.active.first ? Of course, we could use stub_chain, but that doesn''t let us know *where* the chain broke. Would you like to do this?

...ges are not very helpful in cases where a check is incorrect but matches something that occurs in a later block: the checker continues assuming that the matched line is correct (no matter how much farther ahead it occurs) and then provides a misleading error message some time later. The problem is exacerbated if many similar tests are put in one file, since many checks can end up succeeding with unintended matches before something ends up failing. I propose a simple addition to FileCheck syntax to improve error messages in this case: a CHECK-UNIQUE directive which indicates that a given check is a uniq...

...quot; say? And can you run "kinit" to ensure you have a valid ticket? One of my favorite failures is when the time settings between the local host, and the Samba or AD server, have drifted from each other. There are a lot of very awkward and inconsistent NTP or chronyd settings out there, exacerbated when people point NTP to only one server and that server is inaccessible to one or more hosts. > > I must precise we use pam_sssd against Samba4/AD to authenticate. > > Here is my /etc/sssd/sssd.conf: > > > Hmm, I wonder if sssd is getting in the way ?

hello, i have a problem with my dovecot installation. sometimes, the thunderbird clients on windows machines complains about: "server is not imap4 compatible". on the server, at the same time, i found this error: Apr 20 16:21:17 harlock dovecot: imap-login: Disconnected: Shutting down: rip=192.168.0.194, lip=10.70.0.1, TLS handshake the imap server is behind a dmz which sometimes

...e to make changes to src/pkg1/man/foo.Rd and have dependencies that indicate only codoc and examples need to be re-run, not tests and vignettes. (R CMD check can to do this, the problem is moving the appropriate new pieces, in the appropriate way, into the pkg1.Rcheck directory.) The difficulty is exacerbated for me because I have pkg3 depends on pkg2 depends on pkg1. If I make a change to src/pkg1/inst/doc/guide.tex then I really should only need to re-do the vignettes for pkg1, but instead I have to re-do the whole "R CMD check" for pkg1, pkg2, and pkg3. Suggestions would be appreciated. T...

...is working extremely well. We've already done an emergency failover to the warm-backup servers with an acceptable amount of data loss - mostly nothing! I have found; however, a race condition exists between users and rsync that causes a 'vanished file' error. This race condition is exacerbated when the link speed between the systems is slow such as a T1. rsync -avpozO -e ssh /somedirectory/ backupserver:/somedirectory/ During normal system operation, users are allowed to delete files that they own in 'somedirectory'. This is especially true in /home. When rsync is instantia...

...frustration is at a high point as a result of these combined factors, causing many involved to question even the very best of decisions. I suspect that the many requests for ETAs are exacerbating the issue that the CentOS developers simply cannot predict a final release date, which is further exacerbated by the otherwise noteworthy, high-quality QA now in place, which is causing requests for build changes that delay the release and cause need for further QA checks on packages rebuild due to deps changes. It's a perfect storm of factors that, together, result in the current situation. I'...

...s. The easiest way to do this might be to look at the maximum of the covariance of the input/output, or find the phase offset of the input and output FFTs. Maybe it already does this, and someone can say if so? P.S. The above situation is almost exactly what happens on my Mac, and would be exacerbated by people with third party sound cards. ------------------------------------------------------------------------ Zack Morris Z Sculpt Entertainment This Space zmorris@zsculpt.com http://www.zsculpt.com For Rent ---------------------------------------...

Hello. I'm having serious issues with ext3; any insight would be greatly appreciated: _____ Overview: I believe ext3 is supposed to be recoverable in the case of a power failure by replaying the log. However, on two separate computers (running different operatings systems too), this has been everything but the case. _____ Specifics: Sometimes, my kernel will hard-freeze and I'll

Paul, The proposition under discussion is this Deleting UB, rather than warning about UB, should not be the default, as this is contrary to the essentially universal software engineering practice of writing software that is compiler warning free, static analyzer warning free, and dynamic analyzer warning free. This is based on the assumption that in order for llvm to be useful to its
