I have a bit more information on this problem. When I use
debug-on-error, I get the following backtrace:
Debugger entered--Lisp error: (wrong-type-argument sequencep
ess-r-customize-alist)
ess-setq-vars-local(ess-r-customize-alist)
ess-dump-object-into-edit-buffer("LQ")
funcall-interactively(ess-dump-object-into-edit-buffer "LQ")
command-execute(ess-dump-object-into-edit-buffer)
which I don't think helps too much. However when I inspect the variable
ess-source-directory during my R seesion, I see this:
ess-source-directory is a variable defined in ‘ess-custom.el’.
Its value is (lambda nil (concat ess-directory "Src/"))
Original value was "/tmp/"
It seems odd that the value has changed to (lambda nil ...
instead of (lambda () ...
Doesn't the lambda() function need the () in order to be recognized as a
function?
Has anyone on the list been able to get this expression to work or is it
a real bug in ESS?
Thanks for any time you can spend helping me with this.

I have had the following lines in my emacs init.el file for years:
(setq ess-source-directory
(lambda ()
(concat ess-directory "src/")))
This had been taken from ESS documentation from long ago and still
appears in the current documentation. But now it causes a problem.
ESS loads without problem in emacs. However, when I attempt to dump
and edit an existing function (using C-c C-e C-d) while in a running R
process buffer, I get the following message in the mini-buffer and the
dump doesn't occur:
Wrong type argument: sequencep, ess-r-customize-alist
This is frustrating and I've had to resort to dumping files in a
fixed-name sub-directory under my home directory.

Thanks for considering this issue,
