Creating new maps does not work (for me anyways)

[mohelm]

hey - i am trying to have this mapping to send the whole file. but it does not seem to work. can you maybe see why? I would appreciate it thanks a lot.

local r = require "r"

r.setup {
  R_app = "radian",
  bracketed_paste = true,
  view_df = { open_app = "tmux new-window vd" },
  hook = {
    on_filetype = function()
      vim.api.nvim_buf_set_keymap(0, "n", "<localleader>f", "<Plug>RSendFile", { noremap = true })
    end,
  },
}

I do it this way... in my keymaps.lua file:

local function set_rnvim_keymaps()
        -- you can disable keymaps like this:
	pcall(vim.api.nvim_buf_del_keymap, 0, "n", "<leader>rf")

        -- and add keymaps like this:
	local opts_keymap = { noremap = true, silent = true, buffer = true }
	vim.keymap.set("n", "<leader>sb", "<Plug>RSendFile", opts_keymap)
end

-- Then, "load" them based on the filetypes of interest
vim.api.nvim_create_autocmd("FileType", {
	pattern = { "r", "rmd", "Rmd", "rnoweb" },
	callback = function()
		set_rnvim_keymaps()
	end,
})

I hope this helps :)

This is what I am using in the hook:

local map_opts = { noremap = true, silent = true, buffer = 0 }

local function set_keymap(mode, lhs, rhs, opts)
    vim.keymap.set(mode, lhs, rhs, opts or map_opts)
end

set_keymap("n", "<leander>-sb", "<Plug>RSendFile", { silent = true })

many thanks! but does the documentation not suggests you can do it in the plugin setup directly?
also what is <Plug> here?

[PMassicotte]

I do it in setup like you did!

hm i think i got it to work for .r files but not for .qmd.

It only works for R files. For Quarto, we have <LocalLeader>qr ("Send to R: quarto::quarto_render()") and <LocalLeader>ch ("Send all chunks of R code from the document's begin up to here").
