Dear list, I have a list, as follows : a <- 5 names(a) <- "a" b <- 9 names(b) <- "b" c <- 15 names(c) <- "c" x <- list("i" = a, "j" = b, "j" = c) I want to invert the list, like this : $a i 5 $b j k 9 15 I do not find a clean solution. Could anyone give me elegant ideas ? Thanks in advance, Carlos

...as planning to implement a profile guided optimization technique in LLVM. In the open source projects list of the LLVM site; I saw "code layout" is a transformation that can be worth looking at as it will use of profiles (possibly path profiles). So I was thinking of implementing either Pettis-Hansen's (Profile guided code positioning, Pettis & Hansen) or Gloy's (Procedure Placement Using Temporal-Ordering Information, Gloy, Smith) procedure placement algorithm in LLVM because first of all I have not seen any implementation of it in LLVM till** and second, these are the cla...

Hi, I would like to learn the details regarding what exactly PGO does for basic block layout/code placement optimizations in llvm. Could you please point me to some descriptions? Is it close to this paper (Karl Pettis and Robert C. Hansen. 1990. Profile guided code positioning. PLDI'90) http://perso.ensta-paristech.fr/~bmonsuez/Cours/B6-4/Articles/papers15.pdf? Whether it is purely intra-procedural or include inter-procedural optimizations? Thank you so much! Best regards, Xiaowan -------------- next par...

Hi, I'd like to rank obs in a data frame as subset by 2 or more columns... The example input would look like the following: ====+====+====+====+ x y v -- -- -- a w 200 a w 100 b w 500 b w 200 b z 300 b z 400 ====+====+====+====+ And the data frame I want to create is below: ====+====+====+====+ x y v rank -- -- -- ---- a w 200 1 a w 100 2

Hi, I am trying to use R at work and at home on the same computer. At work, I have a proxy, and at home, I do not. I have, for work, a User environment variable "http_proxy" which I set in the OS (Windows XP Pro). When I am at work, and I try to retrieve data from the web with 'read.csv', things work just fine. I assume it knows how to use the proxy. The trouble is when I

Hi, I have a dataframe that has a column of vectors that I need to extract off the character string before the first '.' character and put it into a separate column. I thought I could use 'strsplit' for it within 'transform', but I can't seem to get the right invocation. Here is a sample dataframe that has what I have, what I want, and what I get. Can someone tell

Hi, I want to sort a data frame by multiple columns and then take the first record in each unique level of the "by" group I used to sort the data frame. Does someone have an example of how to do this? Thanks, Matt -- It is from the wellspring of our despair and the places that we are broken that we come to repair the world. -- Murray Waas

The title says it all. Does anyone know of a way to save your packages when you upgrade to a new version of R? This may seem petty, but I'm accumulating enough packages that having to download and install each of them anew every time I install a new version of R is rather of a pain. Ideally, I would like the new version of R to recognize the packages I've installed on the

Hi all, I am trying to run a two factor anova, but one of the factors is a random factor, now I am also running in SPSS and it seems its dividing by the wrong term to get the appropriate F term. here is my data. In SPSS the F scores about double the ones in R, how can I specify one of my factors as a random factor or change it to where it does the right model fitting? I am using the lm command
