...tallation into /lib (now /lib contains jri.dll, JRI.jar and R.dll) and wrote an simple test application that simply calls a command and does not do much parameter assignment (except strings and simple integers) -- all worked fine. Now I want to feed data as a dataframe to R. I thought I can make RVector objects, create RList objects from that and create REXP dataframes from those lists. I found an example here: http://code.google.com/p/jamsim/source/browse/trunk/JAMSIM/src/org/jamsim/r/RInterfaceHL.java?spec=svn52&r=52 ... RList rlist = new RList(vectors.size(), true); ... // turn the rlist...

...ch R objects, or call back into R, for fear of any assignment or allocation triggering an R event. R being single-threaded it cannot do this. My answer to this problem is to only use non-R data structures. That is what RcpParallel does in the actual parallel code portions in all examples -- types RVector and RMatrix do NOT connect back to R. There are several working examples. That is also what the OpenMP examples at the Rcpp Gallery do. Charles seems to be replying 'but I use XPtr' or 'I use XPtr on arma::mat or Eigen::Matrixxd' and seems to forget that these are proxy objects to...

...eans 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 general XPtr objects in Rcpp. Some readers here may recognize my question on SO ( http://stackoverflow.com/questions/37167479/rcpp-parallelize-functions-that-return-xptr) where I was curious about parallel calls to C++/Rcpp functions that return XPtr objects....

...That explains much more of what I was looking for from the R side. Dirk, I'm sorry if I seem hung up on anything here but I am trying to understand the details. My reply about XPtr or XPtr on arma/Eigen was to confirm my understanding was correct, which it appears it was. I was not aware the RVector/RMatrix objects don't connect to R as I am just now familiarizing myself with the package, that explains more of my confusion. I will look at doing work within the compiled code as you have suggested. Regards, Charles On Thu, May 12, 2016 at 9:18 AM, Dirk Eddelbuettel <edd at debian.org&gt...

Hello, All: ????? Is Java being deprecated for R? ????? I ask, because I've been unable to get rJava 0.9-11 to work under either macOS 10.15 or Windows 10, and I can't get rJava 0.9-12 to install -- and my Ecfun package uses it:?? I can't get "R CMD build Ecfun" to work on my Mac nor "R CMD check Ecfun_0.2-4" under Windows.? Travis CI builds
