Roger
Roger is a Go RServe client, allowing the capabilities of R to be used from Go applications.
The communication between Go and R is via TCP. It is thread safe and supports long running R operations synchronously or asynchronously (using channels).
Roger is a work in progress, currently supporting string, string array, double and double array response types. With the use of JSON, this capability can be used to transfer any serializable object.
##Example
package main
import (
"fmt"
"github.com/dareid/gore"
)
func main() {
rClient, err := gore.NewRClient("127.0.0.1", 6311)
if err != nil {
fmt.Println("Failed to connect")
return
}
value, err := rClient.EvaluateSync("pi").GetResultObject()
if err != nil {
fmt.Println("Command failed: " + err.Error())
} else {
fmt.Println(value) // 3.141592653589793
}
helloWorld, _ := rClient.EvaluateSync("as.character('Hello World')").GetResultObject()
fmt.Println(helloWorld) // Hello World
arrChan := rClient.Evaluate("Sys.sleep(5); c(1,1)")
arrResponse := <-arrChan
arr, _ := arrResponse.GetResultObject()
fmt.Println(arr) // [1, 1]
}
##Setup Rserve should be installed and started from R:
install.packages("Rserve")
require('Rserve')
Rserve()
More information is available on RServe's website.
If you would like to exploit the current R environment from go, start RServe using the following command:
install.packages("Rserve")
require('Rserve')
run.Rserve()
Install Roger using:
go get github.com/senseyeio/roger
