Hi, In some cases the number of arguments passed as ... must be determined inside a function, without evaluating the arguments themselves. I use the following construct: dotlength <- function(...) length(substitute(expression(...))) - 1L # Usage (returns 3): dotlength(1, 4, something = undefined)...

Am am missing something or does the new ...names() in R-devel not work right? > a <- function(x, ...) ...names() > a(a=stop("a"), b=stop("b")) [1] "a" "" > a(stop("x"), stop("unnamed"), c=stop("c"), d=stop("d")) [1] NA...

I want to make a glm and then use predict. I have a fairly small sample (4000 cases) and I want to train on 90% and test on 10% but I want to do it in slices so I test on every 10th case and train on the others. Is there some simple way to get these elements? Stephen -- 21/10/2005 [[alternat...

I am interested in creating multiple (say 1000) time series, from a given stochastic process, of length 250. I want to refer to each realization with its own variable name, of the format say, tsn, where n is the n'th simulation. i.e. ts1, ts2, ts3, ts4, .... , ts1000 The way I am thinking of doing thi...

Hi! It's me again with another --link-dest issue: I am using dirvish (www.dirvish.org) to create daily backup on disk images. dirvish is using rsync with --link-dest pointing to the last good image. This creates images with hardlinks to unmodified files. So far so good. Now I want to create a "current"...

Hi, It would be great if one of the experts could comment on the difference between Hadley's dotlength and ...length? The fact that someone bothered to implement a new primitive for that when there seems to be a very simple and straightforward R-only solution suggests that there might be some gotchas/pitfalls with the R-o...

This should (hopefully) be a pretty simple task. What I'd like to do is read in a csv file containing means and standard deviations for a large number of 'n' parameters (up to 2000). The list would be in the following format (see attached read.csv): Paramter(1), mean, standard dev., Paramter(2), mean, standard dev., Paramter(3), mean, standard dev., ... Paramter(n), m...

Hi all, This is a design change proposal to make lld's symbol resolution phase mostly-concurrent without changing the existing semantics. The aim of this change is to speed up the linker on multi-core machines. *Background:* Even though many parts of lld are multi-threaded, the symbol resolution phase is single-thread...

In R-3.5.0 you can use ...length(): > f <- function(..., n) ...length() > f(stop("one"), stop("two"), stop("three"), n=7) [1] 3 Prior to that substitute() is the way to go > g <- function(..., n) length(substitute(...())) > g(stop("one&qu...

Hello all, I'm trying to use cor.test across a range of values via the apply command, c <- apply(X,1,cor.test,y) where X is an array, giving me multiple output from cor.test. I can access individual elements of this by e.g. c[[1]] or c[[1]]$estimate or c[[n]] or whatever, but is there a way to get out the vector...

> grep("f[0-9]+=", "f1=5,f22=3,", value = T) [1] "f1=5,f22=3," How do I make the line output c("f1", "f22") instead? (Actually, c(1,22) would be even better).
