ncm completion not showing

[xllvrr]

Recently, the omnicompletion has not been showing
Configuration file is as below, using ArchLinux on the latest kernel right now. Not sure whether it's a problem with the settings or with another plugin. Tried to uninstall some of the plugins I thought might have an issue and reinstalled the ncm2 stuff but doesn't seem to make a diff

call plug#begin('~/repos/plugged')

" ncm2 for Autocomplete
Plug 'ncm2/ncm2' " Snippets for ncm-R
Plug 'roxma/nvim-yarp' " Dependency for ncm2
Plug 'ncm2/ncm2-bufword'
Plug 'ncm2/ncm2-path'
Plug 'sirver/ultiSnips'
Plug 'ncm2/ncm2-ultisnips'
" For R
Plug 'gaalcaras/ncm-R' " Code Completion for R
augroup ncm2
    autocmd BufEnter * call ncm2#enable_for_buffer()
    set completeopt=noinsert,menuone,noselect
    inoremap <c-c> <ESC>
augroup END

Currently, only packages show

@xllvrr, I am experiencing the same. You can take a look at #9 for more info, but I think the best suggestion will be to give r-lsp a try. I switched am using a coc plugin called coc-r-lsp in vimr (no relation to Nvim-R). I am using vimr so I can send code with command enter (like in RStudio on MacOS).
I installed coc via vim-plug and the languageserver R package install.packages("languageserver"), then ran :CocInstall coc-r-lsp, and everything is working OK so far.

I'm having the same issue. Objects in .GlobalEnv appear in the completion box normally, but functions (e.g., read.csv) do not. When you trigger omni completion manually with <C-X><C-O> functions appears as expected.
