Re: [R] R script From PHP
Hello, You might like the php client to Rserve that is part of the next version of Rserve. see http://www.rforge.net/Rserve/svn.html install the last snapshot, and check the client/php/simple.php file If you decide to go this way, then I'd suggest you use the stats-rosuda-devel mailing list for further questions.

Re: [R] R script From PHP
I tried calling R from a shell script and it works. This is an example file
rscript.sh
R --no-save EOT
x-2*pi
print(cbind(x,sin(x)))
quit(no)
EOT
This works perfectly on the Linux machine in which I have logged in via SSH
using the command (./rscript.sh)
I tried running this command using php
html
?php
$output = array();
$$retval = 0;
$a = shell_exec('./rscript.sh'. 21);
//print phpinfo();
print $a;
?
/html
this does not work and gives me this error:
./rscript.sh: line 1: R: command not found
Anybody familiar with this?

Maybe shell_exec('sh ./rscript.sh 21' ) instead, maybe you need to
have the full path of R.
With this design, you are going to start a new R session each time you
want anything to be computed, and you are going to have to format the
result of the R code as a string and parse this string back in php.
You really should look into Rserve and its new php client, which I think
will solve all of these problems at once.
Just download the version 0.6-1 from here :
http://www.rforge.net/Rserve/files/
$ wget http://www.rforge.net/src/contrib/Rserve_0.6-1.tar.gz
# R CMD INSTALL Rserve_0.6-1.tar.gz
start the server
$ R CMD Rserve
grab the php client, and include it into your php application
$ tar zxvf Rserve_0.6-1.tar.gz
$ less Rserve/src/client/php/simple.php
If you try this route, be aware that the php client is very new. also

Re: [R] R script From PHP

change the top line in rscript.sh to R --slave it just gives me a neat
output. I am not sure why running the shell script directly from within the

Re: [R] R script From PHP
Some more development: I found the directory of R in the Root
It is
/usr/bin/R
I did a ls -l R and got this output
-rwxr-xr-x 1 root root 6642 Jan 9 2006 R (This looks like in CHMOD 755
already)
So I modified my shell script
#!/bin/sh
cd /usr/bin/
pwd
R --slave EOF
x-2*pi
print(cbind(x,sin(x)))
quit(no)
EOF
This is returning me the same error when I try to execute it via my PHP
shell_exec('./rscript.sh'. 21);
Error:
/usr/bin ./rscript.sh: line 4: R: command not found
This is really wierd.

Re: [R] R script From PHP
I agree with Romain that you should probably try and get Rserve to work as
that is a much better way. However, to get your commandline version working,
I suggest you use the Rscript comman instead of a bash script. So let's say
you save your R script as a myscript.R file. Then do:
shell_exec('Rscript /path/to/myscript.R'. 21);
If that still gives you an error like Rscript command not found, then you
need to make sure your R bin directory is added to the PATH system variable.
