Hi, I am reporting what seems to be a trivial error in one of the test files (this has been failing for a few days for me): Collecting examples for package 'tools' Running examples in package 'tools' Error: testing 'tools' failed Execution halted gmake[3]: *** [test-Examples-Base] Error 1 gmake[3]: Leaving directory `/usr/local/share/R-devel/tests/Examples' gmake[2]:

Hi, I have spent a few hours on the R-exts manual and the documentation of parse_Rd() (as well as the PDF document in the references), but I still have not figured out what results=rd means. I thought I could use an R code fragment to create an Rd fragment dynamically. Here is an example, in which I was expected the output to be a describe list <DL> in HTML, but it turns out not to be true.

All, I am not understanding the scoping used in foreach when it is used inside a function. I keep getting "could not find function" errors for functions that are in memory when I try to use foreach within a function call. I have a simple example below. "testFun" is in memory and works when called by foreach directly, but when I place foreach in a function called

Dear R users, I am running R-2.15.1 in Linux Slackware64-14.0. Here is my minimal working example: testfun <- function (x) { a <- 0; sapply(X="a", FUN=get, envir=sys.frame(which=x)); } Inside R, that is R called from within a Linux terminal, the following code works: testfun(x=5) print(testfun(x=6)) But within rkward the above code fails and the following works: testfun(x=1)

Dear All, I have three classes of questions about generating random numbers with different packages (windows xp 32bit R). . 1. Suppose I would like to use package *foreach*, can I use current Sys.time as a seed? Although I can get the time up to1e-6 second precesion, the code below dose not work well on a local machine with two cores. ################# library(foreach) library(snow)

Hi Luke, Ah - I see - thank you! This at least points me to a way on how to "fix" this. I tried setting the srcref attribute to NULL, but the hash value is still different and so is the serialization. So this looks like it is one difference, but not all of them Even if all differences were identified - it still leaves me with different behavior between interactive and batch-mode,

Full_Name: Robert Denham Version: R-2.4.1 OS: Windows Xp Submission from: (NULL) (61.88.57.1) R gui exits without warning when I run a function which has an argument with a default that is not found. This was a result of an error in a function I wrote, but I thought that it should exit more gracefully than it does. Here is an example: testfun <- function(aa=aa) { aa <-

No, I do not get the same as you. I have tested with R-devel and R-patched compiled today. When I do R CMD Rd2pdf mpra I get (as reported a few days ago) Hmm ... looks like a package Converting Rd files to LaTeX Error : mpra/man/mpra-package.Rd:6: file './DESCRIPTION' does not exist whereas you (Kurt) reports that this works on zTree. When I do R CMD Rd2pdf mpra/man I get - a

When I run R CMD Rd2pdf on the man pages of a package, ie R CMD Rd2pdf man I get Converting Rd files to LaTeX Warning in parse_Rd("man/mpra-package.Rd", encoding = "unknown", fragment = FALSE, : man/mpra-package.Rd:6: unknown macro '\packageTitle' Warning in parse_Rd("man/mpra-package.Rd", encoding = "unknown", fragment = FALSE, :

While on the topic of Rd macro arguments, it seems that if a multiline argument is supplied, the lines after the first are silently ignored: f <- tempfile() mac6 <- "\\newcommand{\\mac6}{mac6: #1}" cat(mac6, "\\mac6{2*3 2+2 sin(pi) }\n", file = f) rd <- tools::parse_Rd(f) > rd mac6: 2*3 --- Georgi Boshnakov -----Original Message----- From: Tomas Kalibera

Bug or feature? I get the following error from parse_Rd() when a user Rd macro (including system ones) is invoked with empty argument {}, eg \mymacro{}: Error in tools::parse_Rd(fn) : Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'NULL' A full example is further below with the system macro \CRANpkg{}. In this example it doesn't make sense to use empty argument but

Hi, I posted this question to the regular help list, but it seems to be this is probably a question that is better addressed on r-devel. Sorry for the double posting. I am using hash-values to cache certain results in R. This caching also depends on the hash-value of the function that is being cached (calculated using the digest package). I noticed that computations that should already be cached

I was writing Rd documentation for a new package when I came across this issue. Here's the smallest example: > library(tools) > cat("\\examples{x <- '<%=rnorm(1)%>'}\n",file=file.path(tempdir(),'test.Rd')) > readLines(file.path(tempdir(),'test.Rd')) [1] "\\examples{x <- '<%=rnorm(1)%>'}" >

Dear all, Why does not the three-dot accept arguments from the parent environment? I am just confused with this error, can someone give me a hint? > rm(list=ls()) > testFun <- function(a, ...) + { + if(a){ + print(a) + }else + { + print(b) + } + } > > myTask <- function(a) + { + b <- 3 + testFun(a, b = b) + } >

Hi Gabriel, thanks for your reply - it does solve the problem of my toy function, but does come with some other problems though. a) as.list(f)[[1]] yields an expression, not a function. In order to go the route you are suggesting, I would more likely use "deparse" in order to get the original back b) and more seriously - as.list strips the environment of the function (and thus

Apologees the novice question. Currently climbing up the learning curve of R. Suppose I have the following function and the data.frame: testfun<-function(x=1,y=2) x+y testframe=data.frame(col1=c(1,2),col2=c(3,4)) When evaluating testfun, I want to use the default value for y (which is 2) and for x, I want to feed (one by one) the values in col2 of testframe. How can I achieve this please?

Greetings, I am attempting to run a function, which produces a vector and requires two input variables, across two nested factor levels. I can do this using by(X, list(factor1, factor2), function), however I haven't found a simple way to extract the list output into an organized vector form. I can do this using nested loops but it isn't exactly an optimal approach. Thank you

Hi everyone, >From the currently available version of the package VBmix, I would like to retrieve the intermediate .tex file that generates the VBmix-manual.pdf file. Formerly, running R CMD check with --no-clean allowed to get this tex source from a hidden directory : this feature was removed, but can apparently still be accessed through R CMD Rd2pdf --no-clean. Surprisingly, while the

Do I understand correctly that we don't want Rd files to be valid latex ? This seems odd to me. I see that `tools::parse_Rd()` doesn't like `\verb!foo!` so maybe roxygen2 is actually doing the right thing (as opposed to just trying to) ? `parse_Rd() ` is probably what I need indeed, for some reason I hadn't found it, so that should fix my own issue here thanks a lot.

I am trying to use a custom S4 object in my C code and I cannot get the access to its slots working. The following is a toy example, but even this crashes. In R I have: setClass("pd", representation(data="numeric")) x <- new("pd", data=1:5) test <- function(pd.obj) { res <- .C("TestFun", pd.obj) res} test(x) (Of couse
