Re: [R] Calling SAS from R
Did you read the help(system)?
You should use ``/'', not ''\'' for you path delimiter in R.
The following is a simple example for opening a pdf reader.
system(paste('"C:/Program Files/Foxit Software/Foxit Reader/Foxit
Reader.exe"'), wait = FALSE)
It' also easy to modify the example shown in help(system).

Subject: Re: [R] Calling SAS from R
Thank you for your reply.
Because my R program is Chinese version,
I would try my best to translate and specify my question more precisely.
When I type
system('"c:\\Program Files\\SAS\\SAS
9.1\\sas.exe","c:\\entropy\\output7\\scale\\syntax.sas"')
The warning message is as follow,
In system("\"c:\\Program Files\\SAS\\SAS
9.1\\sas.exe\",\"c:\\entropy\\output7\\scale\\syntax.sas\"") :
"c:\Program Files\SAS\SAS
9.1\sas.exe","c:\entropy\output7\scale\syntax.sas" is not be found
When I try
system('"c:\\Program Files\\SAS\\SAS
9.1\\sas.exe"','"c:\\entropy\\output7\\scale\\syntax.sas"')
The warring message is as follow,
The mistake is if (intern) flag <- 3L else { : The argument can not be
interpreted as the logical value.
These commands also don't work outside R, but I also don't know how to
modify.
I guess it's because I lose a command to tell SAS to read the file, but I
don't know how to do this.
Hope it's clear enough.
Can anyone give me some help with this?
Thanks~
Yen

You need to tell us, as precisely as possible,
what "doesn't work" means.
Did R produce warnings or error messages? What were they?
If you run the equivalent command (the same except for
single vs double backslashes and surrounding quotation marks)
"c:\program files\SAS\SAS 9.1\sas.exe" "c:\syntax.sas"
outside of R (in a terminal window or from the "Run" box
in Windows), does it work?

Re: [R] ANNOUNCE--Rdsm package, a threads-like environment for R
I am interested in Rdsm package, but I have no idea about how to use it. Where can I find examples? regards Guo-Hao Huang -- From: "Norm Matloff" Sent: Thursday, March 11, 2010 1:37 PM To: ; Subject: [R] ANNOUNCE--Rdsm package, a threads-like environment for R My long-promised Rdsm package is now on CRAN. Some of you may recall that I made a prototype available on my own Web page last July. This is the official version, much evolved since I released the prototype. The CRAN description states: Provides a threads-like programming environment for R, usable both on a multicore machine and across a network of multiple machines. The package gives the illusion of shared memory, again even across multiple machines on a network. This is based on a similar package I wrote for Perl back in 2002. Rdsm should complement the bigmemory package written by Mike Kane and Jay Emerson. As noted above and in my July announcement for my prototype, Rdsm works across a network of machines, while bigmemory is limited to multicore platforms. On the other hand, bigmemory is capable of handling huge data structures, which Rdsm is not. Rdsm is intended for parallel/distributed computing, while bigmemory is currently used primarily for the problems its name implies. However, if bigmemory is used as a parallel R vehicle on a multicore machine, it may be faster than Rdsm for some applications, given its direct use of bare shared memory; typically, though, they should provide similar performance in such contexts. By the way, I have a prototype of an infrastructure package to facilitate using bigmemory as a parallel R engine.

Re: [R] how can I use R functions in Fortran 90
You can read the manual below.
good luck!
http://www.biometrics.mtu.edu/CRAN/doc/manuals/R-exts.html#The-R-API
For example, suppose we want to call R's normal random numbers from FORTRAN.
We need a C wrapper along the lines of
#include
void F77_SUB(rndstart)(void) { GetRNGstate(); }
void F77_SUB(rndend)(void) { PutRNGstate(); }
double F77_SUB(normrnd)(void) { return norm_rand(); }
to be called from FORTRAN as in
subroutine testit()
double precision normrnd, x
call rndstart()
x = normrnd()
call dblepr("X was", 5, x, 1)
call rndend()
end
Note that this is not guaranteed to be portable, for the return conventions
might not be compatible between the C and FORTRAN compilers used. (Passing
values via arguments is safer.)
with regards,
Guo-Hao Huang

Subject: [R] how can I use R functions in Fortran 90
Hi all,
Is there a way that I can import R functions into Fortran? Especially, I
want to generate random numbers from some not-so-common distributions
(e.g.
inverted chi square) but did not find any routines written in Fortran that
deal with distributions other than uniform and normal.
Thanks.
Anny
