If your local R CMD check works, it should be fine. Rough specifications for the machines running CRAN checks can be found at <https://cran.r-project.org/web/checks/check_flavors.html>. We ought to test our packages on the weakest hardware that could plausibly be used to run our code, but that's not always easy to do. I know I don't always dig out my old Intel Atom ultraportable to run the checks myself. > The second is the runtime that is too long: > * checking examples ... [43s] NOTE > Examples with CPU (user + system) or elapsed time > 5s > user system elapsed > IOPS 10.06 3.35 35.04 Similar NOTEs can be seen about the use of multi-threading, but here the "elapsed" (real, as measured by a clock) time exceeds the "user" (CPU time spent inside applications) + "system" (CPU time spent inside the operating system kernel) time, so the code uses less than 100% of one CPU core on average, which fits comfortably in the 200% allowed by the CRAN policy for examples and tests. Unfortunately, 35 seconds is still too much. > How can I reduce this time? I'm not sure how to reduce the size of my > ExampleTradeData without the check giving errors when running the > example. How does the algorithm work? I've seen it fail due to Proximities being a 0x0 matrix. Can you work backwards from economiccomplexity::proximity() returning a 0x0 matrix to derive the requirements that IOPS places on the dataset? It may help to experiment with sample.int() to subset the rows and see which combinations work. Perhaps you can reduce the dataset to two countries and two products? Have you tried profiling? You can profile your code for both speed and memory use, and replacing less performant idioms with those using less CPU time and memory may solve both the CPU time problem and the OOM-crash problem: https://cran.r-project.org/doc/manuals/R-exts.html#Tidying-and-profiling-R-code > The third note I am unsure what it means: > * checking for detritus in the temp directory ... NOTE > Found the following files/directories: > 'lastMiKTeXException' Have you installed the inconsolata MiKTeX package? https://cran.r-project.org/doc/manuals/R-admin.html#LaTeX-on-Windows Try running R CMD Rd2pdf on your package directory: maybe MiKTeX will pop up an interactive dialog to let you install any remaining missing dependencies. If not, there should be a lastMiKTeXException file for you to read. -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
