Can't load Nvim-R options and find completion files

[c1au6i0]

Hello I am using NeoVim, I have Nvim-R plug installed and operational but I get this error when using ncmR .

[ncmR] Can't load Nvim-R options. Did you install the Nvim-R plugin?
[ncmR] Can't find completion files. Please load the R packages you need (e.g. "base" or "utils").

Completion works for non R libraries and previously used commands.
I looked for "g:rplugin_compldir" as indicated in a previous issue but I did not find it on my system.

Thanks!

Same issue here

[Bartosz1280]

Have completely the same issue. The problem seems to be independent of other plugs and custom configurations.

Not that I hope anyone is still paying attention, but same here.

same issue here --- starting with a fresh init file and still have the issue.
