Capital 'R' file extension not recognized

[PMassicotte]

In R, it is standard practice to use a capital "R" when naming files, such as test.R. However, this seems to cause an issue in this context, as files with this naming convention are not being recognized. Changing the extension to .r resolves the issue (see the attached screenshot).

I suspect this behaviour may stem from this function:

https://github.com/nvim-tree/nvim-tree.lua/blob/010ae0365aafd6275c478d932515d2e8e897b7bb/lua/nvim-tree/renderer/components/icons.lua#L57-L75)

Is there anything I can do on my end to modify this behavior?

Using

    extension = string.lower(extension)

in the function fixes the problem. It comes from the fact that devicons use lowercases for lookup:

nvim-web-devicons/lua/nvim-web-devicons.lua

Line 231 in 56f17de

["r"] = "r",

nvim-web-devicons/lua/nvim-web-devicons.lua

Lines 518 to 521 in 56f17de

	local function get_icon_data(name, ext, opts)
	if type(name) == "string" then
	name = name:lower()
	end

Should be fixed by #503.

I am using the latest commit of https://github.com/nvim-tree/nvim-web-devicons and still have this issue. devicons lowercase the name of the file, not its extension.

Should be fixed, extension has always been missing.
