Rscript.Rd example (PR#9644)
One of the examples in Rscript.Rd seems mis-formatted, in that the
format statement is incomplete:
## Not run:
Rscript -e 'date()' -e 'format(Sys.time(), "
Both Rscript.Rd in R 2.5.0 and the version at:
https://svn.r-project.org/R/trunk/src/library/utils/man/Rscript.Rd
have
Rscript -e 'date()' -e 'format(Sys.time(), "%a %b %d %X %Y")'

Cannot use setClass() in Rscript
Greetings,
I am creating a standalone executable script using Rscript and have run
into problems when I define a new S4 class. Here is a small script that
demonstrates my problem:

Rscript Bug Report (improper parsing of [args])
Hi,
A user of my `optparse` package discovered a bug in Rscript's parsing of
[args]. (https://github.com/trevorld/optparse/issues/24)
I've reproduced the bug on my machine including compiling and checking the
development version of R. I couldn't find a mention of it in the Bug
Tracker or New Features.
Can be minimally reproduced on the UNIX command line with following

RScript.exe and map directory issue
Hi,
I'm trying to run on Windows 7 a scriptfile with Rscript.exe from within
Excel 2010 with the following code:
Call Shell(rPath & "\Rscript.exe C:\Work\Latest\_Test.R", vbHide)
The good news is: the above code works perfectly, but ...
If I add white spaces to my map directory, like:
Call Shell(rPath & "\Rscript.exe C:\Work\Latest 1\_Test.R", vbHide)

A question about using getSrcDirectory() with R/Rscript
Good morning R-help,
I have an idiot question: I would like to use getSrcDirectory()
and friends to allow me to identify where an R file has been
called from when invoked using Rscript. If I understand the
documentation correctly, the following example should work:
In file test.R:
options(keep.source=T)
fn<-function(x){x<-x+1}
srcDir<-getSrcDirectory(fn)
print(srcDir)

problem with Rscript
Hi all, this is probably some tricky configuration file problem, but I
figure someone here might have come across this in the past:
In short, I've been using Rscript to run my scripts, usually
successfully. But recently I've run into a strange problem, and the
only function that causes an error is "print".
I can create a file that contains only a print command, and it causes

Bug in RScript.exe for 3.5.0
Hi R Developers,
I have found what I think is a bug in the RScript.exe in version 3.5.0 of R for Windows.
When I call Rscript.exe for Version 3.5 of R, it is unable to open the file if the file name or path has a space in it.
As an example of what happens, I saved 2 files with the code:
cat("What do you get when you multiply 6 * 9?")
as C:\foo bar.R and as C:\foo_bar.R

regenerate Rscript after moving R installation
L.S.
In this bug report
https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14493#c1
it is mentioned that after moving an R installation
one should regenerate the Rscript executable.
Is there an easy way to do so (after an R installation has been
moved)?
I have not found any information in the R installation and
administration manual.
Many thanks in advance for any pointer.
Best wishes,

last user argument missing from Rscript --verbose
The loop that echoes the arguments almost always stops too soon. It apparently does that to avoid
echoing the "--args" (that had been inserted) when there are no user arguments. However, when there
are user arguments, the next element of the 'av' array is the last argument and usually not "--args",
although it can be.
?Rscript is a little sketchy:

Exit status of Rscript
Current R release (3.5.2) and devel return a 0 exit status on error,
while prior versions returned a non-zero exit status. On Linux and
MacOs, the following line returns TRUE for R-3.5.2 and R-devel, and
FALSE for R-3.5.1 and R-3.5.0:
system2("Rscript", c("-e", shQuote("stop('foo')"))) == 0
I didn't find this in the NEWS, so I believe this is a bug.

names in Rscript -e
Hi,
I seem to have a problem when passing named parameters to R via Rscript (R2.5.1, bash shell). As soon as I name elements of a list Rscript generates an error.
I will appreciate if someone could point to me a correct way of doing this.
Thanks,
Vadim

Problems with Rscript executable.
Good Morning,
I have recently built R version 2.7.0 on a CentOS release 4.6, 64-bit
system using the following command:
./configure --prefix=/usr/local/r-2.7.0
Everything built fine and works properly except for Rscript which is
looking for files in the original build directory instead of the
specified install directory. Did I forget to add a flag or is this a bug?
TIA,
Gregg.

Why Rscript behaves strangely with file name starting with 'size'?
Hello All,
It seems weird to me that Rscript does the following thing and enters
the R prompt mode. If I change the file name to something that doesn't
start with 'size', then Rscript runs normally. Does anybody know what
is going on?
$ Rscript size.R
WARNING: '--file=size.R' value is invalid: ignored

Rscript path problem on R 2.13.1 for Ubuntu 11.04?
Dear all,
finally decided to do an Ubuntu upgrade and a new clean R install from

However, while trying to install a package from R-forge I encountered
problems, involving error messages saying "Rscript execution error: No
such file or directory" (see below).
The same procedure works on Ubuntu 11.04 running R 2.12.1-1 from the

#!/usr/bin/env Rscript --vanilla ??
I think that's my first true question (rather than answer)
to R-help.
As R has, for a long time, become my primary scripting and
programming language, I'm prefering at times to write Rscript
files instead of shell scripts, notably when R has nice ways to
do some of the things.
On a standard standalone platform with standard R,
I would start such a script with

Rscript -e does not accept newlines under Linux?
Hello,
I have found what I believe to be a bug in the Linux version of the Rscript binary.
Under Windows (official 64-bit 3.5.1 R distribution running on an up-to-date Win10), I can do the following (e.g. under powershell):
PS H:\Users\Cesko> Rscript -e 'ls()
>> ls()'

which works as I expect: I am running Rscript with two arguments, namely (1)
