Below is code that introduces a list comprehension syntax into R, allowing expressions like: > .[ sin(x) ~ x <- (0:11)/11 ] [1] 0.00000000 0.09078392 0.18081808 0.26935891 0.35567516 0.43905397 [7] 0.51880673 0.59427479 0.66483486 0.72990422 0.78894546 0.84147098 > .[ .[x*y ~ x <- 0:3] ~ y <- 0:4] [,1] [,2] [,3] [,4] [,5]...

Dear RHelp-list, ?? I try to use the package comprehenr to replace a for loop by a list comprehension. ?I wrote the code but I certainly miss something because it is very slower compared to the for loops. May you please explain to me why the list comprehension is slower in my case. Here is my example. I do the calculation of the square difference between the values of two vectors vec1 and vec...

Laurent, Thank you for introducing me to a package I did not know existed as I use features like list comprehension in python all the time and could see using it in R now that I know it is available. As to why you see your example as slow, I see you used a fairly complex and nested expression and wonder if it was a better way to go. As you are dealing with an interpreter doing delayed evaluation, I can imagine...

Dear all, my colleague (a statistician - not yet using R) aked me, if there is a R package comparable to the software "PASS" (Power Analysis and Sample Size Procedures), comprising about 150 procedures. I found the R package "pwr". Are there other (more comprehensive) power analysis packages? Many thanks! Udo

Hi all, I'm looking for a package that will give me comprehensive set of descriptive statistics, including skew and kurtosis. Also, is there a similar package that will provide multivariate descriptive statistics as well?

Hello listmates, I know this may sound stupid... but I am trying to set up a firewall/filter/forwarder using CentOS 5.5 machine as a platform and I am succeeding but only partially. Fro example, I am literally trying to forward HTTP and HTTPS (TCP 80 and 443) from the public interface to a private IP and TCP 80 works like a charm whereas TCP 443 seems to be a no-go. To that effect: does anyone

Good Afternoon, I have been looking for a comprehensive list of error codes that are returned by rsync for a script that I am writing.

Hi all, sorry for being OT but would any of you recommend a ticketing system? We'd like something pretty comprehensive to cover helpdesk and HR stuff as well as software bugs/requests. There seems to be a million variations out there.

Just wondering, what exactly is supported/suggested: I need a comprehensive desktop search functionality. Not only searching for file names but also for content and meta data. The environment is EL6.8 / Gnome2. I have noticed that "beagle" is not part of the distro anymore. Any suggestions for such requirement? Thanks! LF

Hi, There is a typo in $LLVM_SRC/Makefile.rules on line 750 where it says : SharedLibKindMessage := "Lodable Module" instead of SharedLibKindMessage := "Loadable Module" Op 15-nov-06, om 15:54 heeft Bram Adams het volgende geschreven: > Didn't check > LLVM's test suite.

Yes that would be a good idea as a separate patch. I'm always annoyed
