...ly inspect? Otherwise, you'll need to debug the code by adding print statements. Something clearly is not as you expect, so you need carefully empirically verify your assumptions about the inputs to and environment of the function.

Does anyone else have any thoughts about troubleshooting the R CMD check environment?

...'s variable administration is such that the order of (un)making them from compiled code matters). I am not very savvy on Rcpp or XPtr objects, but it appears that Dirk provided answers about that in your SO-question.

R Developers, Could someone help explain what it means that R is single threaded? I am trying to understand what is actually going on inside R when users want to parallelize code. For example, using mclapply or foreach (with some backend) somehow allows users to benefit from multiple CPUs. Similarly there is the RcppParallel package for RMatrix/RVector objects. But none of these address the

Greetings, I am collaborating with developing the bigmemory package and have run in to a strange problem when we run R CMD CHECK. For some reason that isn't clear to us one of the examples crashes stating: Error: memory could not be allocated for instance of type big.matrix You can see the output on the Travis CI page at https://travis-ci.org/kaneplusplus/bigmemory where the error starts

...in to plain C++ data structures and go to town in parallel via OpenMP and other multithreaded approaches. Then collect the result, release the mutex and move back up. I hope this help.

This is strictly a curiosity question. I am aware the R doesn't possess a float data type. I also don't mean to request that such functionality be implemented as I'm sure it would require a large amount of work with potential back compatibility conflicts. But I wanted to know why R has never had a float data type available? Regards, Charles [[alternative HTML version deleted]]

...dy ever considered it worth the effort to fully implement the single precision storage. If you mean something else other than the above by "float data type" then please give us more details so that we can better answer the question.

Dear R users, I am happy to announce the most recent version of gpuR has been released. There are several new enhancements to the package including the ability to use user written OpenCL kernels. A full list of changes from the NEWS are shown below. API Changes: 1. deviceType, gpuInfo, cpuInfo not longer accepts 'platform_idx' parameter as OpenCL contexts cannot contain more than one
