Hello! I have noticed that mapply() drops names in R 2.3.1 as well as in r-devel. Here is a simple example: l <- list(a=1, b=2) k <- list(1) mapply(FUN="+", l, k) [1] 2 3 mapply(FUN="+", l, k, SIMPLIFY=FALSE) [[1]] [1] 2 [[2]] [1] 3 Help page does not indicate that this should happen. Argument USE.NAMES does not have any effect here as it used only in a bit special

Looks like the c(x)[...] bit used to be as.matrix(x)[...]. Not sure why the change was made many years ago, but this was before names were handled explicitly. It would definitely be better to not force the duplicate, at least in the case where we are sure c() and [ would not dispatch.

Hi all, I was just wondering if this is the intended behavior. Here is my setup: controller def index respond_to do |f| f.xml { render :xml => true } f.html { render :layout => :none } end end In my views I have a file for each type index.herb index.xerb The first request I send is cached and interferes with the other one. For example, if I send an xml request

barchart(Titanic, stack=F) produces a very nice horizontal barchart. Each panel has four groups of two bars. barchart(Titanic, stack=F, horizontal=F) doesn't produce the results I would have expected, as it produces this warning message: Warning message: y should be numeric in: bwplot.formula(x = as.formula(form), data = list(Class = c(1, And it results in each panel having 22 groups of

Hi I have a matrix "u", for which diag() gives an error: u <- structure(c(5.42334674128216, -2.31319389204264, -5.83059042218476, -1.64112369640695, -2.31319389212801, 3.22737617646609, 1.85200668021569, -0.57102273078531, -5.83059042231881, 1.85200668008156, 11.9488923894962, -3.5525537165941, -1.64112369587405, -0.571022730886046, -3.55255371755604,

Is there a tidy way to get the names of objects passed to a function via the "..." argument? rbind/cbind does what I want: test.func1 <- function(...) { nms <- rownames(rbind(..., deparse.level=1)) print(nms) } x <- "some stuff" second <- "more stuff" test.func1(first=x, second) [1] "first" "second" The usual

It would be possible, but I think "entirely" wrong. .subset() is documented to be an internal function not to be used "lightly" and more to the point it is documented to *NOT*

I would like to suggest a slight modification to diag(). In the case where x is a matrix with both row names and column names the same, it would be reasonable if the resulting vector also had those names. I often use diag() on variance matrices, where this modification is helpful. The modification requires replacing if (is.matrix(x) && nargs() == 1) return(c(x)[1 +

Okay. So, after having spent quite some time never really tracking down why my package NEWS files were unacceptable to readNEWS(), I noticed that there was recent (to me anyway) development that allowed the NEWS to be done as an Rd file. Sweet! A more standard format... I converted a NEWS file in one of my unreleased packages to Rd format. checkNEWS() gave it a thumbs up. But then it went south.

Hey All, I was wondering if I could solicit a little input on what I'm trying to do here. I have a list of matrices, and I want to set their dimnames, but all I can come up with is this: x <- matrix(1:4,2) y <- matrix(5:8,2) z <- list(x,y) nm <- c("a","b") nms <- list(nm,nm) z <- lapply(z,function(x)dimnames(x)<-nms) As you can see, this

Hello, What is the fastest way to do this? I has to be done quite a few times. Basically I have sets of 3 numbers (as characters) and sets of 3 dashes and I have to store them in named columns. The order of the sets and the column name they fall under is important. The actual numbers and the pattern/order of the sets should be considered random/unpredictable. Sample data: vec =

I've been studying some of the code and I'm still a little shakey on the proper method for returning a data.frame from a C function (which is my ultimate goal here). I've started some code that I've "stolen" from the archives and I'm running into crashes, etc. I've been trying to gleen some insight from the src/main/scan.c file and didn't find many comments in

Hi, I apologize if this topic has been discussed - I could not figure out a good search phrase for this question. I have a named vector x, with multiple (duplicate) names, and I would like to obtain a (shorter) vector with non-duplicate names in which the values are the means of the values of the duplicated indexes in x. My best (fastest) solution to this was this code: nms <- names( x )
