similar to: should system.file(package="no such pkg", "no such file") warn or abort?

In R's sprintf() if any of the arguments has length 0 the function aborts. E.g., > sprintf("%d", integer(0)) Error in sprintf("%d", integer(0)) : zero-length argument > sprintf(character(), integer(0)) Error in sprintf(character(), integer(0)) : 'fmt' is not a non-empty character vector This comes up in code like x[nchar(x)==0] <-

Bill, thanks for reporting, this is currently true for all PACKAGES.gz files my autobuilder is creating, will investigate.

Is it just me, or did a corrupt PACKAGES.gz file get installed in the bin/windows/contrib/3.2 directory of CRAN mirrors recently? gzfile() complains about it and Cygwin's gzip cannot decompress it. I tried the following repos <- "https://cran.rstudio.com" v <- "3.2" pkgs.gz <- paste(sep="/", repos, "bin/windows/contrib", v,

While you are fiddling with stopifnot(), please consider changing the form of the error thrown so that it includes the caller's call. The change would be from something like stop( <<the message>> ) to stop(simpleError( <<the message>>, sys.call(-1))) For the following code f <- function(x, y) { stopifnot(x > y) x - y } g <- function(x,

Good Morning, I'm trying to install the rJava package on a local (work) machine and having some trouble. The following occurred in an RGui session. > sessionInfo() R version 2.13.0 (2011-04-13) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=English_United States.1252 LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 LC_NUMERIC=C [5]

Hi, I want to implement a '[' for an S4 class, that behaves differently when called with a single index argument or multiple indexes (possibly missing), like what happens when subsetting matrices x[i] vs. x[i, ]. I manage to do it using nargs() and checking if drop is missing (see code below), but when I want to add an extra argument to the method (before drop), then the parent call

Dear Tony, thanks for the tip with "nargs", when suitably applied, this answers the problem. The behaviour of "nargs" in S4 methods has some subtleties compared to that in normal functions, as shown in the example below. I admit that this is what had earlier created some confusion about the semantics of "nargs". From the perspective of "nargs" and its

I think the problem in R-devel happens when there are non-ASCII characters in any of the strings passed to gsub. txt <- vapply(list(as.raw(c(0x41, 0x6d, 0xc3, 0xa9, 0x6c, 0x69, 0x65)), as.raw(c(0x41, 0x6d, 0x65, 0x6c, 0x69, 0x61))), rawToChar, "") txt #[1] "Am?lie" "Amelia" Encoding(txt) #[1] "unknown" "unknown" gsub(perl=TRUE,

Hello, JIT compiler interferes with internal R completions: compiler::enableJIT(2) utils:::functionArgs("density", '') gives: utils:::functionArgs("density", '') Note: no visible global function definition for 'bw.nrd0' Note: no visible global function definition for 'bw.nrd' Note: no visible global function definition for 'bw.ucv'

Hello, If repeated calls are made to save() using the same pre-opened gzfile connection to a file, and then the connection is closed, the objects saved by the second and subsequent calls are not correctly restored by repeated calls to load() with a new gzfile connection to the same file. What follows are a session exposing the bugs, analysis (see ANALYSIS), patches (see PATCHES), and a session

The Rd.sty LaTeX package is used when building the R manuals, and by the LaTeX pages produced from the man pages. I have tracked down some problems G?bor Cs?rdi was having recently (see "Re: [R] preformatted and '#' in manual pages" in R-help) to a LaTeX problem, and am trying to work out how to fix it. Specifically, the .Rd file he was using had a structure like \dQuote{

I initially sent this to the biocore mailing list - but it was suggested that r-devel would also find it interesting. Many of us use a macro like #define CALL_DEF(fname, nargs) { #fname, (DL_FUNC)&fname, nargs} for use in function registration for use with .Call. For example, using the example from R Extension manual, if we want to register a C function myCall with three arguments, we

I don't know if this is a bug per se, but an undesired behavior in read.dcf. read.dcf takes a file argument and passes it to gzfile if it's a character: if (is.character(file)) { file <- gzfile(file) on.exit(close(file)) } This gzfile connection is passed to readLines (line #39): lines <- readLines(file) If no newline is at the end of the file, readLines

Just wondering if this is the expected behaviour. I was wanting to produce quoted text within \code{}, without manually entering the '"'. \dQuote{} seems advisable after reading the Writing R Extensions manual, so I tried \code{\dQuote{mytext}} expecting it to produce "mytext" in monospace font (with ' ' round it in the R help files) but it appears that

I tried different versions of sma**.tar.gz file either with "R CMD INSTALL -l packagepath sma**.tar.gz", "R INSTALL -l path sma**.tar.gz" and under R windows by "install.packages("sma_0.5.15.tar.gz",repos=NULL)" .

Dear expeRts, The order in which the variables vary in expand.grid() is often unintuitive. I would like to suggest a 'method' slot for expand.grid() which requires only very little changes (100% backward compatible) and which allows one to control this order. Please find attached diffs against R-devel. Cheers, Marius ### ./src/library/base/R/expand.grid.R

Dear R-devel, Last week I got several responses to my question about debugging segfaults in my code (original post below). After I changed the S_alloc() calls to Calloc()/Free(), the symptom was gone, but I was told to keep looking. So I did: o Switched to Calloc/Free. Electric Fence did not find any problem. o Put assert(index < bound); assert(index >=0); everywhere in the C routine

Hi all, I used `gzfile` and `gzcon` to read a compressed file but I found that `gzcon` gave me a different result than `gzfile`. It seems like the `gzcon` does not handle the data correctly. I have posted an example below. In the example, a portion of a compressed file is downloaded from Google Cloud as a raw vector, and the data is saved into a temp file. If I use ` gzfile` to read the file, it

Does anyone notice r-devel thread "stopifnot() does not stop at first non-TRUE argument" starting with https://stat.ethz.ch/pipermail/r-devel/2017-May/074179.html ? I have mentioned (function(...)nargs())(...) in https://stat.ethz.ch/pipermail/r-devel/2017-May/074294.html . Something like ..elt(n) is switch(n, ...) . I have mentioned it in
