Hi Martin,
I'm Cheryl Fernandes currently pursuing my Masters Of Computer Science
at the university of Illinois, at Chicago.
I have tried and tried but just cannot manage to find teh solutuon to teh
following problem.
My question is: Can R be interfaced with Java. ??
My dilemma: I'm trying to run the RGui program in WintNT from a Java
application. i;m using runtime.exec()
It opens teh program but after that nothing happens. After opening teh
program i'm passing some commands to R via java's process
OutputStreamWriter. But it does NOT respond to any of teh commands not
even by giving an exception.
Coudl u please let me know if i can pass commandline commands to RGui from
within Java or are there special API's that are available. I know for a
fact taht Java does NOT have API's for R. It does have special interface
API for major programs
like C. Excel, MS-Word
You could probably use the COM interface to R, which is available from CRAN under 'non-standard extensions'. It's still under development but it does some things. I believe there is a set of classes for calling COM from Java under Windows. -thomas Thomas Lumley Assistant Professor, Biostatistics University of Washington, Seattle -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
