Hello,
I may have found the problem, although I don't understand it.
When I commented out the following line in my Rprofile.site file the
problem _seemed_ to disappear.
# ans as shorthand for .Last.value
# makeActiveBinding("ans", function() .Last.value, .GlobalEnv)
What I believe is happening is that your profile sets this up as an
active binding that cannot be assigned to before the .RDate is loaded
and loading the .RData is trying to assign to it. If you want to
avoid the error you can use
## the argument 'v' means assignment to 'ans' will be ignored instead of
## generating an error message.
makeActiveBinding("ans", function(v) .Last.value, .GlobalEnv)
I decided to do this after reading the help for bindenv {base} and the
phrase ". . . experimental interface . . ." JUMPED right out at me.
Again, I don't know if this was _actually_ the cause of my problem but,
I am underway again.
It would probably be best to recommend that the functins used in
active bindings always take one argument and, if assignment is not
supposed to happen, either ignore that argument it it is supplied or
signal an explicit error. I'll look at the help page and think about
appropriate changes.
Best,
luke
Thanx, DaveT.

Subject: Fatal error: unable to restore saved data in .RData
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.
