Hello,
I have a standalone simulation model written in Objective C/Cocoa. Once the
simulations are done, I would like to send the output (a large C array) to
R.app for further analysis and plotting. I'm able to launch R.app from a Cocoa
app by this:
[[NSWorkspace sharedWorkspace] launchApplication:@"R.app"];
But I'm not able to send the C array or in fact any kind of instructions. I
have tried a modified code:
NSBundle *bundle = [NSBundle bundleWithPath:@"/Applications/R.app"];
NSString *path = [bundle executablePath];
NSTask *task = [[NSTask alloc] init];
[task setLaunchPath:path];
[task setArguments:[NSArray arrayWithObject:@"2+3"]];
[task launch];
But it seems that R.app does not understand the arguments of the NSTask. How
from my Cocoa app, can I tell R.app to read a pointer to a C array and convert
it to a R object, and how can I send R instructions?
Before I wrote the Objective C model as a dyn library and I could call it from
R and run the simulations, but because simulations last hours, I cannot use
R.app during that time, so I'm trying to do the reverse, interact with R from a
Cocoa app once the simulations are done. Has anyone done something like that?
Thanks for any help!
Guillaume
