M-x ess-rdired leads to args-out-of-range error

[davidbudzynski]

What did you expect to happen? I expected the M-x ess-rdired command to create a buffer that shows the objects in the R global environment. I expected the buffer to actually show the objects I created.

What actually happened? The R Dired buffer gets created, but doesn't show any of the objects I created. I get an error report.

save-current-buffer: Args out of range: #<buffer  *ess-rdired-output*>, 1, 225
Error running timer ‘ess-rdired-refresh’: (args-out-of-range #<buffer  *ess-rdired-output*> 1 225) [6 times]

Steps to reproduce:

1. Start R (M-x R)
2. Create some objects (e.g., x <- 5)
3. Attempt to run ess-rdired (M-x ess-rdired)
