Hello, I am having trouble installing the package from CRAN. As the package compiles I get: * installing *source* package ‘RDieHarder’ ... ** package ‘RDieHarder’ successfully unpacked and MD5 sums checked checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for

Hi all, The dict package provides a dictionary (hashtable) data structure much like R's built-in environment objects, but with the following differences: - The Dict class can be subclassed. - Four different hashing functions are implemented and the user can specify which to use when creating an instance. I'm sending this here as opposed to R-packages because this package will

Hi folks, Ubuntu 10.04 64 bit Where can I find 64 bit RSQLite? It seems not there; RSQLite: SQLite interface for R http://cran.r-project.org/web/packages/RSQLite/index.html TIA B.R. Stephen L

Seth, I encountered problems installing RSQLite, R-2.7.0, on RHEL4 using Intel 10.1 icc, My sysadmin helped me track down the problem and kindly forwarded me the fix, which corrected the problem. What follows is from the sysadmin. Mark I looked at the error, looks like there is a bug in the source code. I've attached a new tarball, hopefully fixed. I added #include <sys/types.h>

Should functions or the user be responsible for coercing an S4 object argument containing the proper object (and thus should below be considered a bug in the packages or not)? The example is with RSQLite but the same thing happens with RMySQL, and other DBI packages. > library("RSQLite") Loading required package: DBI > m <- dbDriver("SQLite") > con <-

I got hold of the 0.0.7 RDieHarder binary package as zip for Windows from CRANextras but don't know how to invoke its main method dieharder() in R with "file_input" as RNG argument - how to specify path to that input file ? the 0.0.7 as opposed to 0.1.0 doesn't seem to have ''inputfile'' arg for path specification. So is "file_input" prior to 0.1.0

Hi, for 'affxparser' (Bioconductor), we needed a function to test if a certain package was loaded or not, but we did not want to load it if it wasn't, which is why we couldn't use require(). We came up with the following solution: isPackageLoaded <- function(package, version=NULL, ...) { s <- search(); if (is.null(version)) { s <-

As far as I can tell, 'isOpen' cannot return FALSE in the case when 'rw = ""'. If the connection has already been closed by 'close' or some other function, then isOpen will produce an error. The problem is that when isOpen calls 'getConnection', the connection cannot be found and 'getConnection' produces an error. The check to see if it is

Is it possible to override S4 methods in an installed package? The naive library("pkg") setMethod("foo", signature(obj = "bar"), function(obj , x, y) { new definition } , where="package:pkg") results in the error Error in setMethod("foo", signature(obj = "bar"), function(obj, : the environment "pkg" is

Hi I seem to have run into a situation where I have more than 3 arguments to pass to a function from C. the following functions help me build an expression for evaluation: lang lang2 lang3 lang4 What should one do if there are more arguments than lang4 can handle?

Hello, I would like to compress a long string (character vector), store the compressed string in the text field of a SQLite database (using RSQLite), and then load the text back into memory and decompress it back into the the original string. My character vector can be compressed considerably using standard gzip/bzip2 compression. In theory it should be much faster for me to compress/decompress

I was hoping someone could tell me how to convert multiple C character strings into an R character vector.

I created an add-on R package. In this package, there is a line "require(pckgname)", because I need to call some functions in pckgname. My package is successfully built and can be successful installed. But R CMD check can not be executed. The error message is: * checking package dependencies ... ERROR Packages required but not available: pckgname Actually, before running R CMD

I think Rscript has a problem running files that have mac encodings for newline (^M rather than ^J on linux). If I source the file within R, it works okay: > source('j.R') [1] "MEA_data/sernagor_new/CRX_P7_1.txt" But if I run the file using Rscript on a linux box I get a strange error message: $ Rscript --vanilla j.R " Execution halted The example script j.R is at

Is it safe to call setGeneric twice, assuming some setMethod's for the target function occur in between? By "safe" I mean that all the setMethod's remain in effect, and the 2nd call is, effectively, a no-op. ?setGeneric says nothing explicit about this behavior that I can see. It does say that if there is an existing implicity generic function it will be (re?)used. I also tried

Currently library() and attach() fail to locate an existing '.conflicts.OK' in a package wit name space, unless it is exported. Since there should be little interest in exporting '.conflicts.OK' otherwise, one may argue that those methods should look for '.conflicts.OK' even if it is not exported. If so, a patch for library() is: >svn diff library.R Index: library.R

Hi, from 'Writing R Extensions' [R version 2.11.0 Under development (unstable) (2010-03-16 r51290)] one can read: "The optional `Imports' field lists packages whose name spaces are imported from but which do not need to be attached. [...] Versions can be specified, but will not be checked when the namespace is loaded." Is it a design decision that version specifications

Hi the list, I am writing a package that happen to not be compatible with linux because I did not know that the function "savePlot" was available only on windows. Is there a list of "incompatible" function? How can I get this kind of information? Thanks Christophe

It appears that the runtime for an R script can more than double if a few references to a function foo() are replaced by more explict references of the form pkgname::foo(). The more explicit references are of course required when two loaded packages define the same function. I can understand why use of this mechanism is not free in an interpreted environment like R, but the cost seems rather
