Hi,
I met tough problems when calling R in PHP. I have tried several ways, but none
of them succeed.
first of all, I tried Rserve, but I failed to connect to it.
Then, I tried cmd.exe. I get the result when I use" R CMD BATCH
--vanilla..." in cmd, but I have no idea how to call cmd in php.
I know "system()" is good to call other systems, I triedbut I get no
result in my html page.
if you could provide some suggestion or examples, i would appreciate your help.
the code in my php is：
$cmd="R CMD BATCH--vanilla --slave delete.r";
$res=system($cmd);
the code in the delete.r file is:
setwd("c://wamp//www//analysis");
x<-4;
y<-3;
z<-x*y;
sink("125.txt");
png(file="125.png");
barplot(z,border="dark blue")
title(main=list("earning of comparison",font=4));
plot(x,z);
dev.off()

While someone around here might know about PHP (I don't h, the fact that you
don't know how to call system suggests that you should be asking in a PHP
help forum.
Rserve can be used for interactive sessions, but web services usually aren't
designed that way, so you probably want to call R with batch arguments the same
way you would call it from the command interpreter, but not actually via the
command interpreter.

Hi, rapache.net is definitely worth to check. And also "rook" from the same author (Jeffrey Horner).
