I get the same error in a bash session on a Mac. My assumption at this
point is is that the authors of Rscript decided that you should
already know what is in the input file and so left out that feature of
the console program. Mavbe if you explained why you wanted what would
generally be a straight copy of the input file, someone can offer a
work-around strategy.

Hi,
I run Rscript from the command line (bash). My OS is the following
$ cat /etc/redhat-release
CentOS release 5 (Final)

I can use savehistory in an R session (that is after the R prompt
'>'). My file 'savehistory.R' only have the following three lines.
f=tempfile()
f
savehistory(f)
I run the command 'Rscript savehistory.R' from the bash command line,
which gave me the error I showed in my previous email. Can somebody
try if he/she receives the save error?
Regards,
Peng

You did not make it clear (to me anyway) what computing environment
the
Rscript command was issued from. I assumed probably incorrectly
that you
were doing this from inside an R session and did not understand
that Rscript
was an external program. If I was wrong about that, then you are
going to
need to provide more details about your operating system and how
you have
set up your R installation.
I also do not know what you mean by a "save session". Did you at
some time
in the past execute a savehistory(file="savehistory,R") command at
the end
of a session and it's now in the directory that Rscript look for?
That would
be the only way that a savehistory.R file would exist.
So what OS? What did you do before this failed effort? And what are
you
really trying to do?
Then perhaps someone familiar with your OS can answer.

You should be looking for .Rhistory
Some OSes make that task difficult. "savehistory" is not the file
name
but
rather the name of the function that performs that operation. Try
savehistory(file="text.Rhistory") and see if the history file is
easier
to
find. Should be in your working directory.
Rscript is a program, not a record of the prior session.

Hi,
I run the following command and try to save the commands that have

it because that the history is not recorded in Rscript?
