After digging around in the sas.get code, I found a change that seems to
be causing the problem:
old version:
...
status <- sys(paste(sasprog, sasin, "-log", log.file),
output = FALSE)
...
new version:
...
status <- sys(paste(shQuote(sasprog), shQuote(sasin), "-log",
shQuote(log.file)), output = FALSE)
...
For some reason, sys() bombs when given a command string with quotes in
it. The string works fine when pasted into a command line window, so
maybe it's a problem with the WinXP commmand interpreter? In any case,
changing the sys() call to system() seems to fix the problem.
...
status <- system(paste(shQuote(sasprog), shQuote(sasin), "-log",
shQuote(log.file)))
...

Subject: Re: [R] Problem with sas.get function in Hmisc
The workaround you point seems to be the solution for the moment.
I not sure I will have time (and courage) to try to figure out where
the bug comes from. Hope a more literate R programmer than me is
willing to dive in...
Thank you for your answer.
2006/12/12, Agustin Calatroni <acalatro at rhoworld.com>:
Jean, I saw your email to the R-help mailing list. I also notice the
problem a few months back and email the maintainer (Charles Dupont)
but
never got a response. Since I used the function a lot and in order to
avoid the error I use version 3.0-12 instead of updating the a newer
version. To download the earlier version use the following site:
http://cran.r-project.org/bin/windows/contrib/2.2/ If you figure out
another way around the problem I will be interested in knowing the
solution.
Sincerely,
-- Agustin Calatroni

I been having the following problem when I updated the Hmisc package
from version 3.0-12 to version 3.1-1.
Create dataset under SAS:
data a;
do i = 1 to 100;
x = rannor(0);
output;
end;
run;
Hmisc version 3.0-12:
library(Hmisc)
sas.get('C:\\Documents and Settings\\novell\\My Documents\\SAS
Temp\\_TD3428','a')
NO PROBLEM
Hmisc version 3.1-1:
library(Hmisc)
sas.get('C:\\Documents and Settings\\novell\\My Documents\\SAS
Temp\\_TD3428','a')
The filename, directory name, or volume label syntax is incorrect.
Error in sas.get("C:\\Documents and Settings\\novell\\My
Documents\\SAS
Temp\\_TD3428", :
SAS job failed with status 1
In addition: Warning message:

Thanks for Hmisc and Design packages, they are an invaluable
resource.
Sorry if this is a stupid question and I missed something obvious.
