[ESS] R Transcript opens in readonly buffer

[Ishe Chinyoka]

Hi,

 I am having a problem whereby if I save a .Rout transcript,
when I try to open it next time, I cannot edit it. It opens the buffer
in readonly mode. What could be the cause of opening in readonly mode? I
wnat to continue working on some transcript in a new session.

I am using emacs 29 and ESS version 18.10.3snapshot on Archlinux.

TIA,

Ishe
