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).

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

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 0.2303 0.3618

Dear R help I have conducted a fa() analysis, and I want to use fa.diagram to assess the extent to which the 11 latent 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

Hi there, I'm new to this list, and in fact rather new to the Ogg/Vorbis codec altogether. I recently downloaded the test files from the test conducted by the German computer magazine c't (this was mentioned by someone here recently). The idea was that you were given seven WAV files each for 64kbps and 128kbps, and had to rate them. The files were randomly chosen for each participant.

Hi R forum, Each row of my data (below) show a new contact event between animals. In order to ultimately look at the patterns of intervals between contacts, I need to calculate a contact end time. The contact starts at the date and time shown in V4 and V5, and lasts for the duration shown IN SECONDS in V6: > data2<- read.csv(file=file.choose(), header=F, sep=" ") >

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?

Hi, Apologies if this has been proposed before; I couldn't find anything in basic searching. I've been writing tests lately and noticed that the error messages 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

...15 to 1.0.15. after the upgrade i was forced to enhance the proc.sys.fs.inotify.max_user_instances = 1024 because i had error messages about "Inotify instance limit for user exceeded" my question is: does the upgrade triggered a new way of communication between clients and server that exacerbates the problem of dropped connections from the DMZ server? p.s. the dovecot configuration is: $ sudo dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/harlock_digicert_2009.pem ssl_key_file: /etc/ssl/priva...

I am trying to re-organizing my Makefile for testing my R packages and I am having trouble finding a structure I like. The problem seems to be that "R CMD check", which does wonderful things, does not allow dependency information to flow through very gracefully. That is, since everything is copied into the pkg.Rcheck directory, it is difficult to make any changes to source files without

Hi Rsync/Samba team, First of all, cudos on rsync 2.6.6! It is running exceptionally well. I'm using a script executed by cron to keep warm-backup servers in sync with the primary server. The execution is set to run every 5 minutes. Like any good programmer, this process is *very* paranoid and uses 'wall' to notify the users if any error occurs during the transmissions. This is

As the OP for this thread, it saddens me to see that the thread I started has now been used as a forum for behavior of the worst kind seen in professional circles. I'm a longtime user of CentOS and merely wanted to know of users' past experiences transitioning between SL and CentOS. My first experience with CentOS was as a transition from Whitebox to CentOS, and the process was as

...TOH, does a large amount of IPO and IPA, such as dead argument elimination, IPSCCP, and other things. Something that is good to inline for GCC is not necessarily good for LLVM. 3. Once these annotations are added to a source base, they are almost never removed or reevaluated. This exacerbates #2. In my mind, the right solution to this problem is to use profile-directed inlining. If you actually care this much about the performance of your code, you should be willing to use profile information. Profile information will help inlining, but it can also be used for far more than just...

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
