Hello,
I am hoping to post to the right mailing list, if not apologies!
I have recently written my first couple packages, relying on devtools and
roxygen. Everything is done in RStudio (details regarding the setup: see end of
text).
But the help is not working! Specifically:
On Windows 7:
* functions: I cannot click the links in the 'help'-panel. Or at least nothing
happens when I click them.
* DESCRIPTION: If I build the package locally, it has the same issues as the
packages. If I install the packages from Github (devtools::install_github) or
from a network drive, it works.
* The "my_package::my_function" syntax throws an error. Once I enter 'my_package::' and click TAB,
the following error appears in the console: "Error in gzfile(file, "rb") : cannot open the
connection"
* "?my_package::my_function" brings me to the function overview page for the
package, but not to the help page for the my_function()
* the link itself (on the function overview page) looks inocuous:
http://127.0.0.1:44391/help/library/helpers/html/my_function.html
I would love to do a Traceback on this, but I do not know how, since it only happens when hitting
TAB. I have done a Traceback for "?my_package::my_function", it just returns the path to
where the help should be, like "D:/Home/R/Rpackages/my_package/help/my_function".
On MacOS Sierra:
* DESCRIPTION can always be opened, no matter how the package is installed
* when clicking on functions in the help panel, the known error appears (as text in the help
panel): "Error in gzfile(file, "rb") : cannot open the connection"
It gets much weirder: When installing the package for the very first time, it
seems to work! But after that it quits working, even not when I delete the
package, re-install R, re-install RStudio, and create the package from scratch.
I really wish I was kidding with all of this. I have tried every debugging-idea
that came to my mind, including (but not limited to):
* the .Rd-files are generated, they definitely are not missing
* taking an auto-generated DESCRIPTION file
* removing every function file save for a test file
* copying content from a function file into the auto-generated "hello.R" file
* changing the encoding from UTF-8 to WINDOWS-1252
* as mentioned, trying everying both on Windows and MacOS, and trying different
ways of installation
* as mentioned, re-installing both R and RStudio
I would enormously appreciate it if anyone has an idea how to get a handle on
this, any suggestions are welcome!
Nothing that you've written is reproducible by others. See if you can
put together a short self-contained series of instructions that display
the problems (or just one of them). It might involve installing from
Github, or making a package tarball available somewhere.
