Current core/Recommended Matrix package (0.999375-48) has been segfaulting against R 2.13-alpha/2.14-trunk for the last week or so (since R-2.13 was branched, when I started trying) when "run with R CMD check --use-gct": -------------- > pkgname <- "Matrix" > source(file.path(R.home("share"), "R", "examples-header.R")) >

Hello, I'm having some difficulty to understand how I could take the proper result from the following listing: -- cut --- #include <stdlib.h> #include <R.h> #include <Rmath.h> void retMat ( double **y, int *n, int *m, double *a, double *b) { int i, j; y = malloc( (*n) * sizeof( double ) ); for (i=0; i<*n; i++) { y[i] = malloc (

Hi, I am making multiple calls to gzfile() via read.table(), e.g. > x <- read.table( gzfile( "xxx.gz" ) ) After i do this many times (I haven't counted, but probably between 50 and 100 times) I get the error message: Error in open.connection(file, "r") : unable to open connection In addition: Warning message: cannot open compressed file 'xxx.gz' however, I

Hi, the following example aiming at a class containing a logical slot segfaults under R-1.9.0 when `gctorture(on = TRUE)' is used: Code code (dummy.c): #include <Rdefines.h> SEXP foo() { SEXP ans; PROTECT(ans = NEW_OBJECT(MAKE_CLASS("test"))); SET_SLOT(ans, install("lgl"), allocVector(LGLSXP, 1)); LOGICAL(GET_SLOT(ans,

When I read a .gz file with readLines() in 3.4.3, it returns text (and a warning). In 3.5.0, it gives a warning, but no text. Is this expected behavior or a bug? 3.4.3: > source_file = "1k_annotation.gz" > readfile_con <- gzfile(source_file, "r") > readLines(readfile_con, n = 5) [1] "#chr\tpos\tref\talt\t <truncated output here> Warning message: In

If I open a tgz archive with gzfile and then parse it using readLines I miss the initial line of each member of the archive - and also the name of the file although the archive otherwise complete (but useless!). Is there any way within R to extract both the list of files in a tgz archive and to extract any one of these files? Clearly I can use zcat and tar on Linux, but I need this to work

Hi all, I am not able to export an ALTREP object when `gctorture` is on in the worker. The package simplemmap can be used to reproduce the problem. See the example below ``` ## Create a temporary file filePath <- tempfile() con <- file(filePath, "wrb") writeBin(rep(0.0,10),con) close(con) library(simplemmap) library(parallel) cl <- makeCluster(1) x <- mmap(filePath,

Hello ... Are there any known problems or even gotchas to look out for when using a gzfile connection in read.csv/read.table in Windows? In the package PROcess, available at www.bioconductor.org/repository/devel/package/html/PROcess.html there are two files in the PROcess/inst/Test directory which are of the extension *.csv.gz. With both files, if I open up a gzfile connection, say: vv <-

I've forgotten to submit this as bug report (and haven't easily seen how to debug). The bug is both for is.na() and is.nan() {which makes much sense since the C code of the two is very similar!}; only one is shown below.

Hi, I have some text files that do not have trailing \n on the last (incomplete) line; how do I read in the last line? e.g. here is a test case: [linux + R version 2.6.1 (2007-11-26) ] z <- gzfile("short.gz", open="w") cat("7\n5\n3", file=z) close(z) z <- gzfile('short.gz') readLines(z) [1] "7" "5" readLines would indicate that

Hi, I'm running into more issues when reading data from a gzfile connection. If I read the data sequentially with successive calls to readBin(), the data I get looks ok. But if I call seek() between the successive calls to readBin(), I get corrupted data. Here is a (hopefully) reproducible example. See my sessionInfo() at the end (I'm not on Windows, where, according to the man page,

I get unexpected behavior from "readLines()" and "scan()" depending on how the file is opened with "gzfile" or "unz". More specifically: > file <- gzfile("file.gz") > readLines(file,1) [1] "a\tb\tc" > readLines(file,1) [1] "a\tb\tc" > close(file) It seems that the stream is rewound between calls to readLines.

Hi I have been trawling the web, FAQs, and R manuals for help on the following issue, but have failed and was wondering if anyone has a solution to the following problem: After having installed R 2.6.2 for Windows (binary), I tried to install various packages. Every time I try loading a package (any package) via the built-in menu, I run into the following error message. >
