js-call-r | Javascript call R function with a simple way | Runtime Evironment library

I finally found the solution for my problem. Actually r-script or js-call-r didn't help me calling R function. Here is what I did:

I used plumber package on R, so it creates a localhost so I could call my R functions via http request. Full documentation is on their website but here are the steps I took to set it up:

a- Open R Gui (64bit) Note: if you don't have R, go download it from: cran.r-project.org/mirrors.html

b- If you don't have plumber package, install it with R GUI with command: install.packages("plumber")

c- To check if R Gui root directory is at the file you want, send command: getwd()

d- If it's not the path you want, change it with: setwd("C:/your/Desired/Path")

e- Copy your R file into the same directory that you set in previous step

f- Send this command to start reading your R file: pr <- plumber::plumb("YourRFile.R")

g- run this command so it will run the local host: pr$run()

h- it should give you the port number so you can send receive messages
