R vs SPSS output for princomp
Hi, I am using R to do a principal components analysis for a class which is generally using SPSS - so some of my question relates to SPSS output (and this might not be the right place). I have scoured the mailing list and the web but can't get a feel for this. It is annoying because they will be marking to the SPSS output. Basically I'm getting different values for the component

assigning from multiple return values
I know that if I have a function that returns multiple values, I should do return(list(foo, bar)). But what do I do on the recieving end? fn <- function(x) { return(list(foo, bar)) } I know that at this point I could say values.list <- fn(x) and then access values.list[1] values.list[2] But that's hideous. I'd rather be able to say something like list(local_foo, local_bar)

Could not destroy domain, current job is remoteDispatchConnectGetAllDomainStats
Hello libvirt-users list, We're catching the same bug since 3.4.0 version (3.3.0 works OK). So, we have process that is permanently connected to libvirtd via socket and it is collecting stats, listening to events and control the VPSes. When we try to 'shutdown' a number of VPSes we often catch the bug. One of VPSes sticks in 'in shutdown' state, no related 'qemu'

barplot default colors
Dear R-help, Can some one explain why barplot() uses changing colors in the bars by default? I should think that most of the time when people draw barplots, they want the bars to be in the same color. (At least that's what I'd expect. The first time I used barplot() in R, I was shocked to see the colors.) As an example, one example in ?layout draws a scatterplot with histograms drawn

GVIM annoyances

TCNG issue - parent class restrictions are not honored
Hi, I''ve been migrating an existing htb-based traffic shaper from a hideous (I''m allowed to call it that - I wrote the damn atrocity myself) tc shell script into a TCNG configuration file, and after a few false starts I think I managed to get the syntax right. However, during tests it looks like some of the tiers aren''t passing their restrictions on to lower levels.

Hangups after voicemail
Hi, Try as I might, I can't get hangups detected on a Zap channel with loop start lines. So, after someone leaves a voicemail and then hangs up, Asterisk doesn't know it, exits VoicemailMain2, and loops back to the corporate greeting, tying up the line even though the outside caller has hung up. Therefore, I've added the following hideous hack - er, code - to voicemail2.c. It

why results from regression tree (rpart) are totally inconsistent with ordinary regression
Hi, In my analysis of impacts of insecticide-treated bednets on malaria, I look at the relationship between malaria incidence and mosquito behaviors. The condensed data set is copied here. Ordinary regression (lm) shows that Incidence was negatively related to Mortality. This makes sense because the latter reflected the strength of killing mosquitoes by insecticide-treated nets. Since the

ActiveRecord::DangerousAttributeError ???
Hi, For some reason, this harmless block of code in my application controller def index @wide = true end is causing this hideous error. I have read the error means that the error is raised when attribute has a name reserved by ActiveRecord. Does that mean that none of my models can have columns named "toggle"? Here is the error and framework trace:

Plotting individual survival plots
Using the survival library, it is possible to get a plot of all the subjects in a sample and it is possible to get a plot of all subgroups in the same plot. How does one get a separate plot for each subgroup? plot(survfit(Surv(time,death==1)~group),col=1:10) The above results in a hideous graphic representation. I would prefer to specify par(mfrow = c(2, 5)) and have each plot separately --

Previously compilation procedure on Mac OS X no longer works
Hi, I was a happy user of Peter Parks' package (see http://www.chip.org/ ~ppark/Supplements/PNAS05/) and could compile it without error under Mac OS X 10.4. I then had a disk crash and had to re-install the developer tools and now I get hideous messages such as the one below. I have tried installing an earlier version of Mac OS X developer tools.
