Interfacing Go and R

[ljw...@gmail.com]

Is there a library or other preferred method for interfacing golang programs to R?  

(Sorry if this has been asked and answered elsewhere: R is the only programming language in the world harder to Google than Go. Googling them together is fun :)

Thanks.

Not that I know of. I looked a while back and didn't find anything so I ported my R code to Go (not for the faint of heart). The use of "CRAN" is probably highly correlated with the R programming language, and on the second page of results for the query "golang R CRAN" I found this:

It may not be what you need, but I hope this helps in your search. It does not look like there is much out there. Good luck.

fwiw I was doing some modeling this summer and wrote scripts in R and executed them from Go using os/exec. rjson makes it possible to encode your R objects in JSON which you can demarshall in Go. These may help:

What exactly are you trying to do in R?

I had a student start writing an Rserve interface for Go, but they found
other work. Rserve is likely to be a cleaner route to interoperation
with R. The start of that package is available if you want it (it's not
in a usable state yet).

Where is said package available?

I am toying around with some kind of "table dumper" which

converts Go slices to R data frames. It is Go to R only but

works for me to plot Go produced data via ggplot2.

Intention was to open source it once I'm no longer

ashamed of API, code and documentation :-)

Package is a very strong word. I can post you the code (I have it in an email) after I ask him if it's OK to let others see it. There are significant design decisions to be made in how type interchange operates between R and Go (Go does not natively support all R numeric values and how the interchange API should work is not immediately obvious - the java Rserve client may help designing this).

I was looking to make a Go Rserve client, so it would probably be beneficial to see progress others made so far.

If there happens to be a possibility of seeing this code publicly, please let us know.
