display_id: Starting display ID
max_attempts: Number of displays to try

Details

When reconnecting a tmux session, the R session may no longer be able to open an X11 window. In such cases, the display ID may have changed between the R session opening and the tmux session reconnecting. This function iterates over the displays until one can be used or max_attempts is reached.
