The easiest solution
The easiest solution would be just create a
config.R (or something like that), and read the file in R.
For example here is
= in Python):
#file: config.R user <- "root" password <- "root" host <- "localhost" dbname <- "pokemon"
And then, read it by
source("config.R") in R or
from config import * in Python.
Generic solution compatible with other languages
However, if you want to share the config file with other languages, the solution above doesn't work any longer.
So to make the config more generic, use YAML. Much like any languages, both R and Python have a decent library to handle YAML file.
Here is a
year: 2017 db: user: root password: root host : localhost name: pokemon
In R, use
library("yaml") config <- yaml.load_file("config.yml") class(config) # "list" config$year # 2017 config$db$user # "root"
In Python, use
import yaml with open("config.yml") as fp: config = yaml.safe_load(fp) type(config) # dict config["year"] # 2017 config["db"]["user"] # "root"
