All,

I try to run Zorro 1.42 with the laters R 3.2.5 on windows 10.

To do this, I installed both programms and added the right path to the zorro.ini file.

RTermPath = "c:\Program Files\R\R-3.1.3\bin\i386\Rterm.exe"

When I run the RTest script in Zorro it fails.

Did anybody see this behavior? How can I fix this?

Thanks in advance.

Jack

Your RTermPath does not lead to R 3.2.5. Perhaps you have updated your R installation, but not your Zorro.ini file?

That is a correct observation.

I first installed the newest R and the newest Zorro. Then I tried to configure the R bridge with the RTermPath variable in the Zorro.ini file.

Because that did not work, I thought it might be the R version. Because Zorro.ini points to the older version I downloaded that and installed it. So I really have the older R release installed and I am pointing to it correctly.

Jack.

In addition to the previous...

I tried to install the newest zorro and R on another machine. I changed the line for RTermPath into the following:

RTermPath = "C:\Program Files\R\R-3.2.5\bin\i386\Rterm.exe"

It still does not work. Is there a way to get some logging out of the zorro process to see what happens?

Jacco.

R 3.2.5 works fine with Zorro. Here's a script that produces some diagnostics at start:

Windows sometimes goes strange ways. I often face problems with applications installed in "\Programm Files" because of special NTFS settings. I installed R directly in C:\\R\... and had no problems anymore.

All,

First of all, thanks for all the support. I think there is something wrong when zorro tries to run R with the command Rrun.

I slightly modified the print statements in the script above and I added the r.h include. It now looks like:
#include <r.h>

function main()
{
if(!g->sRTermPath) {
printf("R path missing! ");
return;
}
if(!file_date(g->sRTermPath)) {
printf("%s not found! ",g->sRTermPath);
return;
}
string Cmd = strf("Command : %s --no-save",g->sRTermPath);
printf(Cmd);
hR = RInit_(Cmd,2);
if(!hR) {
printf("Can't initialize RTerm! ");
return;
}

Rx("rm(list = ls());"); // clear the workspace

var vecIn[5],vecOut[5];
int i;
for(i=0; i<5; i++)
vecIn[i] = i;

Rset("Rin",vecIn,5);
Rx("Rout <- Rin * 10");
Rv("Rout",vecOut,5);

if(!Rrun())
printf("\nError - R session aborted!");
else {
printf("\nReturned: ");
for(i=0; i<5; i++)
printf("%.0f ",vecOut[i]);
}
}

The output is:
Zorro 1.42.2 Trading Automaton
Made with Gamestudio by oP group 2015

testREnv compiling.................
Command : C:\R\bin\x64\Rterm.exe --no-save
Error - R session aborted!

So the script aborts when running the Rrun() command.

Just to make sure, I now installed R in C:\R as shown in the output. My RTermPath is:

RTermPath = "C:\R\bin\x64\Rterm.exe"

Both the x64 and the i386 do not work.

Jacco.

Ok, so R was correctly initialized, but then terminated for some unknown reason. Can you replace the line

Rx("rm(list = ls());");

with

RExecute(hR,"rm(list = ls());");
printf("\n%s",RLastOutput(hR));
if(!RIsRunning(hR)) {
printf("\nR stopped!");
return;
} else
printf("\nR still running...");

and let me know what it prints?

Hi Chief, ;-)

I changed the script as you indecated and it prints the following:


testREnv compiling.................
Command : C:\R\bin\x64\Rterm.exe --no-save

R stopped!

I tried to run the complete command from a cmd and this start up Rterm.exe
perfectly. I get the prompt and can leave with q() as expected.

From the zorro script Rterm.exe seems to stop as printed by the zorro script.

I hope you have a suggestion of what to do.

Ok, now it becomes a little more complicated since you need to download a tool, the Debug Viewer. You can download it from many places, f.i. here:

https://technet.microsoft.com/en-us/sysinternals/debugview.aspx

Start it with default options. "Capture Win32" should be on. Now start the test script again and post here what the debug viewer prints out.
