Dear UseRs, Could someone explain to me why the default behaviour of rank() is to assign the largest rank to missing data > rank(c(3, 1, NA)) [1] 2 1 3 as opposed to what I would hazard would be the expected 2, 1, NA? Despite consistency being the hobgoblin of little minds, of two closely related functions one handles NAs in the same way (order()) but another one doesn't (sort()).

dear expeRts, i would like to merge the data frame entries in a list. for example: > #input > myl <- list(q1=data.frame(id=c("Alice", "Bob"), grade=c(90, 49)), q2=data.frame(id=c("Alice", "Chuck"), grade=c(70, 93)), q3=data.frame(id=c("Bob", "Chuck"), grade=c(84, 40))) > #output > (mydf <-

Hi, I want to compile the manual for "methods" so that I can have the usual indexed man pages in a single document with a ToC. I've tried with R CMD Rd2dvi --pdf /usr/local/lib/R/library/methods but the result is odd, the ToC shows only "as" and "setOldClass" and it does not compile all man pages, the pdf has only 30 pages ... I know I can simply print

dear list, i am having trouble coloring the bars in a barplot. my data have two groups, which i would like to plot side by side. within each group i want to sort the observations in decreasing order, like a pareto chart. the bar colors would relfect the value of a third variable. below i have generated a reproducible example. the bar heights are a given pig's "gain",

Hi, I'd like to check the existance of a NOT NULL constraint for a given attribute using ActiveRecord. Is this possible or do I have to painstakingly query the information_schema myself? I need this for some reflection in a custom association. Thanks, - Rowan -- Morality is usually taught by the immoral. _______________________________________________ Rails mailing list

dear r-helpers, it seems the colors in an automatically generated lattice legend recycle after the 8th color, even when the user has set e.g. superpose.symbol$col to be longer than 8. the following example will illustrate what i mean: z <- data.frame(x=rep(letters[1:15], each=4), y=rnorm(60), groups=rep(LETTERS[1:3], 20)) library(nlme) library(lattice) plot(groupedData(y ~ x |

Daniel, Nadav, Hal, So, after some painstakingly boring re-formatting, I've split the 24 kernels into 24 files (and left a horrible header file with code in it, which I'll clean up later). Since we're taking times in the benchmark tool, and we're trying to assert the quality of the FP approximation by the vectorization, I'll try to come up with a reasonable watermark for each

Recently I''ve wanted to be able to take the data I''ve painstakingly defined in my fixture files and slurp it up into my development database so I can play with my website (locally, in development mode) with the same data I use in my tests. In a similar vein, I want to take the table definitions in the development_structure.sql file and use it to re-define my development

I've installed fail2ban, it seems to be working as it identified my failed test logins, BUT, my question is: what can I do when I see same invalid name trying to login to dovecot, different IP each time, how can I say block each IP as used by this name ? or it that a bad idea ? I can see two persistent attempts as so: I don't have such user 'ignacio' or 'julian' # grep

hi, can anyone confirm the following problem? when i do dos> rcmd rd2dvi --pdf my-package-name i get dos> Can't open perl script "c:\PROGRA~1\r\rw1091/bin/rd2dvi": No such file or directory might the problem be in (double back slashes rather than forward slashes) R-1.9.1\src\gnuwin32\front-ends\rcmdfn.c(251): strcat(cmd, RHome); strcat(cmd, "/bin/Rd2dvi.sh");

Hi, I'm trying to set up a prediction software, now i testing the performance of my method, so i need to calculate a ROC curve, specially auc, cut-off, sens and spec, i just looking at ROCH package, but it's a mass for me, i'm not a math guy and I'm getting lost Could any of you recommend me an easy-to-use package to do this task? i just have a list of positive/negative samples

Dear all, I'll implement a VoIP system using Asterisk + SIP with softphones; I need to connect LAN and VPN users (about 100-150). What version/installation of asterisk do you recommend tyo me ??? Does Asterisk@Home or Trixbox match to my scenario ???? By the way, I use Debian Etch as OS server. Really thanks. Alejandro --

If I execute R CMD Rd2dvi foo.Rd I get messages of the form: Converting Rd files to LaTeX ... foo.Rd Creating dvi output from LaTeX ... Saving output to 'foo.dvi' ... cp: .Rd2dvi4366/Rd2.dvi: No such file or directory Done xdvi-xaw: Fatal error: foo.dvi: No such file. Indeed if I add the --no-clean flag and then cd to the .Rd2dvi<whatever> directory, I find that there is no

Is there any way of getting just the LaTex output which R CMD Rd2dvi generates on the way to produces a .dvi file, which could then be incoorporated into another document?

I'd like to make MikTeX the default TeX package in 2.2.0, but we still need to let people use other packages. The problem is that MikTeX wants a command line option --include-directory $R_HOME/share/texmf, while other packages specify includes via environment variables, and barf when they see the unexpected option. The choice should be controlled by the user's settings in the MkRules

Hi, I run R 2.5.1 on Mac OS 10.4.10 and fail to build a package manual. Below is the transcript. The problem is a "pdflatex: command not found" error but I think that I have a fully working latex install (installed with iInstaller) as I use TeXShop with no problem. Could someone help?

Hi! I am doing a research about the prices of SIP telephones. If someone can tell me which one are the cheapest and have an acceptable quality... it will be very kind. Best Regards, Mireia

Hello If I'm not terribly mistaken, looks like libvirt 1.2.1 does not provide ability of merging only a subset of the entire chain of backing files. So, if I have a chain like this: root <- a <-b <- c <- d <- active ... and I'd like to obtain a chain like this: root <- c <- d <- active ... looks like it's not supported,
