ISSUE: On MS Windows, running cmd.exe, calling Rscript --vanilla -e "port <- tools::startDynamicHelp(); port; port <- tools::startDynamicHelp(FALSE); port" will sometimes stall R at the end, preventing it from existing. This also happens when running R in interactive mode. It seems to stem from calling tools::startDynamicHelp(FALSE). Before filing a formal bug report, can someone pleas...

Thank you for confirming this. I just filed PR#18650 (https://bugs.r-project.org/show_bug.cgi?id=18650). FWIW, I've found two other issues with startDynamicHelp() prior to this: * https://bugs.r-project.org/show_bug.cgi?id=18645 * https://bugs.r-project.org/show_bug.cgi?id=18648 /Henrik On Sat, Jan 6, 2024 at 5:53?PM Steve Martin <marberts at protonmail.com> wrote: > > Henrik, > > I was able to reproduce this both with Rscript and inte...

...ocumentation has been much ignored). This appears to only be true if the original R session is still active. Close one R session and the links die in the browser. Aahg! What madness! 4. The NEWS file says: o A new dynamic HTML help system is used by default, and may be controlled using tools::startDynamicHelp(). With this enabled, HTML help pages will be generated on request, resolving links by searching through the current .libPaths(). The user may set option("help.ports") to control which IP port is used by the server. This should be 'options', of course. The 'options' pa...

Hi, Each > help.start() generates a new tree of the R help system, somewhere in 127.0.0.1:xxx, each xxx being difeerent. This tree disappears when exiting R. How can the current help tree copied to a permanent place for reference outside a running R? This would be practical for not having to enter M-x R . TIA --Christian -- Christian W.
