Re: [Rd] Set the number of threads using openmp with .Fortran?

I got this to work on Linux but it is not working on Windows. *My understanding is that this should also work on windows, is that correct?* If so, what should I do? differently? To get it to work on Linux, I modified my R script as follows: #' OpenMP Hello World #' #' @param nthreads The number o

Re: [Rd] Runnable R packages

Creating an .exe file isn't necessarily difficult. The main problems are that you have to write and compile the C (or other) files. Otherwise, the complexity depends on the level of Inter Process Communication that's required. Simply starting R with some initial conditions, is easy. Even if you wa

remotes has fewer dependencies. I believe that the current version of devtools just re-exports install_github etc. from the remotes package. On 2019-02-02 11:31 a.m., David Lindelof wrote: > I see some value in Duncan’s proposal to implement this as an extra package > instead of a change to b

I was able to make some progress by using this as a reference. Now: *This is my makevars:* # Compiler flags # PKG_FCFLAGS = $(SHLIB_OPENMP_FFLAGS) PKG_LIBS = $(SHLIB_OPENMP_CFLAGS) # Phony target for R's build s

Re: [Rd] Runnable R packages

I see some value in Duncan’s proposal to implement this as an extra package instead of a change to base R, if only to see if the idea has legs. I’m minded to do so myself using your suggestion, but is there a particular reason why you recommend using the remotes package instead of devtools? The lat
