[Rd] parallel PSOCK connection latency is greater on Linux?

I'm exploring latency overhead of parallel PSOCK workers and noticed that serializing/unserializing data back to the main R session is significantly slower on Linux than it is on Windows/MacOS with similar hardware. Is there a reason for this difference and is there a way to avoid the apparent

[Rd] vignettes present in 2 folders or won't work

Dear all, I am struggling with an issue related to static vignettes: they work, but only when present in double in the tarball -- in the folder inst/doc and vignettes; see below for details. Details: I am pre-compiling heavy vignettes thanks to the vignette builder R.rsp. So basically, I have PD

Re: [Rd] vignettes present in 2 folders or won't work

You are doing a lot of things that are non-standard, so I doubt if anyone is going to be able to help you without access to a simple reproducible example of a package that does what you do. Try to cut out as much as you can to make it minimal. For example, devtools::document() (indeed, most o

Noted Duncan and TRUE... I cannot do more immediately unfortunately, that is always the issue of asking a last minute panic attack question before teaching a course involving the package... I do have /doc in my .Rbuildignore for reasons I can no longer remember... I will dig and create a MRE/repre

Re: [Rd] vignettes present in 2 folders or won't work

I take Duncan's point but would second the motion to have WRE clarify how static vignettes are supposed to work; it's a topic I am repeatedly confused about despite being an experienced package maintainer. If knowledgeable outsiders compiled a documentation patch would it be likely to be cons

The closest to a canonical reference for a static vignette is the basic blog post by Mark at https://www.markvanderloo.eu/yaRb/2019/01/11/add-a-static-pdf-vignette-to-an-r-package/ which I follow in a number of packages. Back to the original point by Alexandre: No, I do _not_ think we can do

Re: [Rd] vignettes present in 2 folders or won't work

CRAN policies say, "neither data nor documentation should exceed 5MB (which covers several books). A CRAN package is not an appropriate way to distribute course notes, and authors will be asked to trim their documentation to a maximum of 5MB."[1] I post R Markdown vignettes as companion
