Weird behaviour with ssh

[stat quant]

For some reason for nvimr to behave correctly ie: open a split tmux pane on Rstart I need to open the tmux session just before using vim.

As opposed to: if I open a tmux session, then ssh to another box, then open vim and RStart. 

If I do this I cannot get R to open in a split pane, it will open in another distinct window (so the plugin still works but the behaviour is not the one I want).

Is this expected ?

Is there a work around ?

This is the expected behavior. The Vim-R-plugin used to save the current Vim session and, then, start tmux running the saved session and finally quit the original Vim session. This was a very complicated procedure that required many global variables to be saved. Each time that I created a new variable I had to remember of adding it to the saved session. So, I removed the feature. If you don't want to start tmux before Vim, you have to either run R in an external terminal emulator or use Neovim instead of Vim.
