[R] Fatal error: unable to restore saved data in .RData

[Thompson, David (MNR)]

Hello,

I am unable to start an R session by double-clicking on an existing
.RData file from the Windoze file explorer.
A dialogue appears with the message
	"Fatal error: unable to restore saved data in .RData",

and I notice in the R Console the last few lines are:
	"Loading required package: R2HTML
	 NULL
	 error in function ()  : unused argument(s) (1:43)"

I tried starting a fresh R session, changing the working directory,
saving a new empty workspace, closing R, and restarting with the new
(empty) .RData file to the same effect.

I tried with the --vanilla option, changing the working directory and
loading the existing workspace,  and get the error message:
	"Error in function ()  : unused argument(s) (1:43)"

And again with the --no-restore-data option, same effect.

Suggestions?
Thanx, DaveT.
