similar to: Bug report: R.home() cause package Rcpp failed executing sourceCpp, similar bug are labeled "BUG 16660" since 2016 and here I could provide a solution that tested in my laptop.

Martin, You are making your life way too complicated. There are a number of things I would do differently: 0) Wrong list. Rcpp has its down, rcpp-devel, and I basically do not read this and would have missed this were it not for luck.

Hello R-devel, Currently on Unix-like systems, Sys.which incorporates the absolute path to the `which` executable, obtained at the configure stage: > ## hopefully configure found [/usr]/bin/which > which <- "@WHICH@" > if (!nzchar(which)) { > warning("'which' was not found on this platform") This poses a problem for the Spack package

But I though it was a developers of the rcpp-package. So it is ok

Hi R-devel, The following code: all.equal(baseenv(), baseenv()) gives the error when run in a clean R session with latest R-devel (r66650): kevin:~$ R --vanilla --slave -e "all.equal(baseenv(), baseenv())" Error in all.equal.envRefClass(target[[i]], current[[i]], check.attributes = check.attributes, : attempt to apply non-function Calls: all.equal ...

Hi all, I'm not sure if I'm not supposed to do the following (the dyn.unload part, I mean) or this could be a bug (in R or Rcpp): ``` Rcpp::sourceCpp(code=' #include <Rcpp.h> class Object {}; //[[Rcpp::export]] SEXP new_object() { return Rcpp::XPtr<Object>(new Object()); }' ) new_object() dyn.unload(list.files(tempdir(), ".(so|dll)$",

I've just committed some changes to R-devel which affect environments. Specifically: - using NULL as an environment is now deprecated: use baseenv() instead. (baseenv() is already available in R 2.2.0, where it returns NULL. For most purposes it retains the same meaning in R-devel.) If you do use NULL, it will be converted to baseenv(), and a warning printed. For example: > f

I understand why the following happens ($.proto delegates to get, which ascends the parent hierarchy up to globalenv()), but I still find it anti-intuitive: > z <- 1 > y <- proto(a=2) > y$z [1] 1 Although this is well-documented behavior; wouldn't it uphold the principle of least surprise to inherit instead from baseenv() or emptyenv()? (See attached patch.) Spurious

With a pretty recent version of R 2.11.0 (devel,unstable, svn 50178) on Linux I could not install version 1.5-8 of zoo (the current on on CRAN): % R-devel CMD INSTALL -l Rlib3 zoo * installing *source* package 'zoo' ... ** R ** inst ** preparing package for lazy loading ** help *** installing help indices converting help for package 'zoo' finding

eapply() works on most environments, but not on baseenv(). For example, > x <- 1 > eapply(globalenv(), function(x) x) $x [1] 1 > eapply(baseenv(), function(x) x) list() I'm probably not going to have time to work on this before 2.3.0, but I don't think it's really urgent; if no one else fixes it first I'll do it after the release.

Hi, I have written a small C++ function and compile it. However in R I can't see the function I have defined in C++. I have read some web-pages about Rcpp and C++ but it is a bit confusion for me. Anyway, This is the C++-code: #include <Rcpp.h> using namespace Rcpp; // [[Rcpp::export]] List compute_values_cpp(int totalPoints = 1e5, double angle_increment = 0.01, int radius =

In trying to change the driver used by Sweave on the command line using R CMD Sweave --driver=foo I consistently get the "directory 'foo' does not exist' error. (For any value of 'foo', even the default 'RweaveLatex'.) Looking up the source code for function .Sweave that is called by 'R CMD Sweave', I notice that the argument 'driver', if

Hi, in help("R_GSCMD") it says "R_GSCMD: Optional. The path to Ghostscript, used by dev2bitmap, bitmap and embedFonts. Consulted when those functions are invoked.". However, if 'R_GSCMD' contains a full pathname to the Ghostscript executable (as above "path" indicates), e.g. > Sys.getenv("R_GSCMD") [1] "C:\\Program

A new release 0.10.0 of Rcpp is now on CRAN, bringing a number of new features to R --- please see the announcement text below. The most direct change may be what we call 'Rcpp attributes' and which is described in a new vignette bringing the total to nine vignettes in the package. Dirk, on behalf of Dirk, Romain, Doug, John and JJ ===== Summary ===== Version 0.10.0 of the Rcpp

I?m wondering which is the most efficient (time, than memory usage) way to obtain a multivariate time series object from a data frame (the easiest data structure to get data from a database trough RODBC). I have a starting point using timeSeries or xts library (these libraries can handle time zones), below you can find code to test. Merging parallelization (cbind) is something I?m thinking at

Dear all, I am forced to work in an environment without administrator rights. When using R2.13.1 on Windows 7 (64-Bit), I found that I can?t install or update any packages due to missing writing permissions. I managed to get full access to a directory on my C:\ drive now - but how do I specify that all libraries shall be installed into this directory? In Rcmd_environ I have the following

Dear List, There seems to be an bug in compactPDF() or at least an inconsistency with the documented behaviour. The documentations states: Details: This by default makes use of ?qpdf?, available from <URL: http://qpdf.sourceforge.net/>, including a Windows binary. If ?gs_cmd? is non-empty, GhostScript is used. I don't have qpdf on my system so planned to use

Those of you who track R development closely, will have noticed yesterday's commit of enhanced versions of nchar() and nzchar(). ------------------------------------------------------------------------ r68254 | maechler | 2015-04-23 18:06:37 +0200 (Thu, 23 Apr 2015) | 1 line Changed paths: M doc/NEWS.Rd M src/library/base/R/New-Internal.R M src/library/base/R/zzz.R M

I would go to the source, in this case Dirk Eddelbuettel's (I hope I spelled it correctly) documentation for Rcpp: http://dirk.eddelbuettel.com/code/rcpp/Rcpp-attributes.pdf Note that you need to do sourceCpp("logistic_map.cpp") in R instead of building and dyn.load()-ing the object.

Dear all, I am trying to use Rcpp to write some files in C++ for use in R. Below is an example for a cpp-file (crossp.cpp). Then I use >sourceCpp("crossp.cpp") in R and the corresponding function is availabe in R. Now I have to question related to this worklfow: 1) Is there a way to see the source file of the "final" cpp-file? (I mean is it possible to see how the
