Greetings and Salutations All,

Isaac, To build off of what Bob mentioned, you may wish to check that Rcpp and RcppArmadillo are indeed installed.

Greetings and Salutations Jon, > Lack of OpenMP support in Apple?s build of Clang is cited as one reason for not using it in CRAN builds

Naeem, The best path for including compiled code in a package is to place it within the `src/` directory instead of using `Rcpp::cppFunction()` to compile. The reasons for this are stated succiently here: https://stackoverflow.com/a/6074391/1345455

Greetings and Salutations Spencer, Modifying the path traditionally was done in `~/.R/Makevars` by setting the implicit variables: `CXX`, `CXX11` , ... I've found a better approach is to modify the `~/.Renviron` file. Since `.Renviron` is a "dot file", macOS will...

All, First, macos-rtools isn't an officially sanctioned R project installer. I created it in the Summer of 2017 to quickly get students and collaborators setup with minimal effort under a configuration that mirrored CRAN. This was primarily due...

Hi all, Henrik Bengtsson has done some fantastic work with {future} and, more importantly, greatly improved constructing and deconstructing a parallelized environment within R. It was with great joy that I saw Henrik slowly split off some functionality of {future...

Erich, Try to install gfortran with this installer: https://cran.r-project.org/bin/macosx/tools/gfortran-6.1.pkg Sincerely, JJB ?On 10/10/19, 10:28 AM, "R-SIG-Mac on behalf of Erich Subscriptions" <r-sig-mac...

Greetings and Salutations All, Recently, I've had the need to collide large matrices 1x10^7 using code written in RcppArmadillo. Initially, I triggered: Error: Mat::init(): requested size is too large; suggest to enable ARMA_64BIT_WORD Upon a...

Greetings and Salutations, The answer is yes, multiple processes can concurrently modify different parts of the object. So, the object is not ?locked.? In this case, it?s important to note the scope of the object being ?shared? and not...

Greetings and Salutations, Odd that the warning would end up being triggered as file is automatically generated with appropriate line endings. Within the package directory, try running: Rcpp::compileAttributes() This will recreate the export files (e.g. src/RcppExports.cpp...

Greetings and Salutations Brook, The segfault is related to `int main() {}`. There is no need to use `int main() {}` unless you want to make this standalone in which case you want to use RInside to embed R within a C...

For those interested, the few other instances can be found by looking under the inst/include/Rcpp/generated/ folder: https://github.com/RcppCore/Rcpp/tree/master/inst/include/Rcpp/generated In the case of Vector__create.h, one would need...

Rainer, Download the R-devel build from http://mac.r-project.org The build is available under "Universal nightly builds for Mac OS X (10.6+ and 10.9+)" table. R-devel-el-capitan-sa-x86_64.tar.gz (67Mb...

Greetings and Salutations All, I think `launchd` jobs would properly sign the installer. `launchd` is Apple's re-envisioning of `cron`. So, would it be possible to port over the cron job to `launchd`? Sincerely, JJB ?On 9/20/19...

All, Hope all is well. About a month or so back, we revisited the **unofficial** macOS R compilation toolchain setup wizard with a focus on making it more maintainable without an Apple developer subscription. The result is the new {macrtools...

For code searches, consider using the {searcher} package: https://github.com/r-assist/searcher In particular, the search_github() function handles the query formatting. As an example, try: searcher::search_github("clusterEvalQ ") This opens a web browser with: https://github...

Roger, Due to macOS Mojave shift where system headers are located, you'll need to run: sudo installer -pkg \ /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg \ -target / This installs the headers back to the default...

Greetings and Salutations Sharat, Could you supply some test data? Sincerely, JJB From: rcpp-devel-bounces at lists.r-forge.r-project.org [mailto:rcpp-devel-bounces at lists.r-forge.r-project.org] On Behalf Of Sharat Sent: Thursday...

Thanks for the reproducible example! Here is the solution: library(Matrix) Omega <- Matrix(c(1,0.8,0.8,1),2,2) invSqrtV <- Diagonal(2,1) Omega.M <- as(as.matrix(Omega),"dgCMatrix") invSqrtV.M <- as.vector(diag(invSqrtV)) partialsolveCS...
