Error: The X Window system is required to run R in an external terminal.

Dear programmers,

thank your for providing Vim-R-plugin.

I have a probably easy and quick to fulfill request:

Running vim in an ssh session from within tmux I would like to have Vim-R-plugin to open a new tmux window for me.
To achieve this, I set the following in my .vimrc:

let vimrplugin_term_cmd = "tmux new-window 'R"

I tried the latter tmux command and it works, i.e. it opens a new tmux window and starts R in there. But unfortunately I get the error "The X Window system is required to run R in an external terminal".

I assume the plugin checks for a running X window system before even trying to start R?
Could you introduce a simple switch to turn that check off, please?
Something like:
vimrplugin_check_x_win_sys = 0

I for one would be very happy, indeed.

Cheers!

I changed the plugin's default behavior recently and now you have to manually start Tmux before starting Vim. Please see #52 and #53 for details.

What you want may be achieved with the following procedure:

1. ssh into the remote machine
2. Start tmux
3. Start Vim (with the R script as the file to be edited)
4. Do <LocalLeader>rf

Please, read about "tvim" in the plugin's documentation to know how to do 2 and 3 at once. What I have written above was already explained in detail in section "Tmux usage" of the plugin's documentation.

I have improved the warning message. Now it is: "Start 'tmux' before Vim. The X Window system is required to run R in an external terminal."

The problem was trivial:

The version to be found in the official vim-scripts Github repository:
https://github.com/vim-scripts/Vim-R-plugin
does not work as expected.

Once I checkout out this development version's master branch,
R is opened in a split tmux window.

Thanks and Cheers!

Hi There, I am still using the previous Vim-R-Plugin version and pretty comfortable about it settings. Recently I upgraded the linux system and got message never before "Start 'tmux' before Vim. The X Window system is required to run R in an external terminal.". The issue is, if I start tmux manually, the vim background were also changed weirdly and furhter ,rc will start a R console in a split window rather than a new window. Do you have some suggestions?
