This is an enquiry not so much about what the code for loadNamespace does, but rather about the intent and design of loadNamespace, and how it interacts with the `::` function, which seems to me to follow a slightly different philosophy. It is not an urgent question - the issue that started me wondering has been resolved another way - but I would like to complete my understanding of this aspect

I notice something curious about how aov() treats a numeric factor: "score" is a dependent variable and "group" is a factor in a one-way ANOVA. But "group" contains numeric codes and is not a factor (checked with is.factor). An ANOVA done using: > aov(score~factor(group), data=mydata) gives the right answers. But > aov(score~group, data=mydata) also

Hello list, I am writing a package which builds on a function ("foo") of another package. I only need that particular function. What is the state of the art to do this? Do I need a NAMESPACE file in my package? Currently I still don't have one. Or can I do this with the Imports field in my DESCRIPTION file? Reading chapter 1 of the "Writing R Extensions" manual I do

I'm trying to build a package. The machine is PowerPC G4 with Mac OS 10.4.8, and I'm using R2.4.1. I get "R CMD build roots" working, and it created roots.tar.gz. But I get the following message when I run "R CMD INSTALL -l ../myrlibrary roots.tar.gz" ====================================================================== * Installing *source* package 'roots'

help(letters, htmlhelp=TRUE) fails. Under the Mac OSX gui, the message is 'Help for the topic "a" was not found.'

Hi All, is there Levene' test in R ? If not ,Could you give me some advice about Levene test with R? Thanks a lot! I am waiting for yours.

Hi folks, R on ESS Why it is unable to pop up help manual on "R on ESS"? ?layout Error in help("layout", htmlhelp = FALSE) : unused argument(s) (htmlhelp = FALS ?plot Error in help("plot", htmlhelp = FALSE) : unused argument(s) (htmlhelp = FALSE) etc. But they work on R console and popup the manual without problem.

Hi all Just this morning I upgraded to R 2.12.0 (for Mac OS X 10.6.4). All went well until I needed to run a help() or help.search() in my session, which I'm running within Emacs (ESS 5.3.7). Say I need help with the command 'density'. When I type help(density) or ?density the ESS help buffer opens, it is titled *help[R](density)* but it contains only a couple of lines saying,

I wonder if anyone who has worked on the win32 version of R could help me with a HtmlHelp question? When you're building a win32 program using mingw (in my case, cross-compiling under GNU/Linux), what import library do you use to link against the HtmlHelp() function? I have got a copy of MS's htmlhelp.lib, but mingw doesn't seem to like this format; it wants an archive in .a format.

Hi all, I want to write a wrapper for an analysis of variance and I face a curious problem. Here are two different wrappers: fun.1 <- function(formula) { summary(aov(formula)) } fun.2 <- function(formula) { oneway.test(formula) } values <- c(15, 8, 17, 7, 26, 12, 8, 11, 16, 9, 16, 24, 20, 19, 9, 17, 11, 8, 15, 6, 14) group <- rep(1:3, each=7) # While the first

Hello R-users! I have a style question. I know that for loops are somewhat frowned upon in R, and I was trying to figure out a nice way to do something without using loops, but figured that i could get it done quickly using them. I am now looking to see what kind of tricks I can use to make this code a bit more aesthetically appealing to other R users (and learn something about R along the

Using => and <= instead of -> and <- would make things easier, although the precedence would be different.

Dear list, This should be a simple one, I just cannot see it. I need to generate a sequence of the form: 4 5 6 13 14 15 22 23 24 That is: starting with 4, make a 3 numbers sequence, jump 6, then another 3 and so on. I can create a whole vector with: myvec <- rep(rep(c(F, T, F), rep(3, 3)), 3) Then see which are TRUE: which(myvec) [1] 4 5 6 13 14 15 22 23 24 I'd like to avoid

R-2.0.0, WinNT / WinXP: options(chmhelp=TRUE) ?dnorm # does not work! ?Normal # works! Looks like calling compiled html help does not work for aliases, but only for the title of help pages... And a quick fix without changing the design is to change lines 136-137 in .../src/library/utils/R/help.R as follows: - err <- .C("Rchtml", hlpfile, topic, - err =

Dear list, Given a list of elements like: aa <- list(one=c("o", "n", "e"), tea=c("t", "e", "a"), thre=c("t", "h", "r", "e")) Is there a function that returns the intersection between all? Both match() and intersect() only deal with two arguments, but sometimes I

Hello, Is there a way to extract multiple columns from a dataframe using their names instead of their numbers? Currently I use: data2 <- data1[, c(1,3,9)] And I am looking for something like data2 <- data1[, c("XX","YY","ZZ")] I use the same dataframe for many purposes, and I run codes that change the order of the columns every time. Many thanks, Adrian

Dear list, I have two functions created in the same environment, fun1 and fun2. fun2 is called by fun1, but fun2 should use an object which is created in fun1 fun1 <- function(x) { ifelse(somecondition, bb <- "o", bb <- "*") ## mymatrix is created, then myresult <- apply(mymatrix, 1, fun2) } fun2 <- function(idx) { if (bb == "o) { #

Thanks Adrian and Thierry (from the previous answer).

I suppose it would work, although "=>" is rather a descriptive symbol and less a function. But choosing between quoting: "A + B => C" and a regular function: A + B %=>% C probably quoting is the most straightforward, as the result of the foo() function has to be a string anyways (which is parsed by other functions).
