They will be retrieved from the stores with something like $

go to settings/secret in your repo and add them.

Renviron file is a simple text file where you can add ‘secrets’ like: apikey="aVerY5eCretKEy" on a new line.

Now this file with secrets will be ignored by git and you.

How do you add them to your local environment? In your script you use Sys.getenv("apikey") and the script will retrieve the apikey: aVerY5eCretKEy and use that. So you create an environmental variable called apikey with a value like aVerY5eCretKEy. So how can you do it? R can read environmental variablesĪnd in github you can input the environmental variables that willīe passed to the runner when it runs (there are better, more professional tools to do the same thing but this is good enough for me). If you put it on github, the world has your secrets (I just did this). Small diversion: credentials/ secretsįor many applications you need credentials and you don’t want to put theĬredentials in the script, if you share the script with someone, they also have the credentials. But this example is relatively small and you can actually see the results online. Of course you could create something that is actually useful, like downloading data, cleaning it and pushing it into a database.

a folder with a script that does what you want to do.

If you are not interested go immediately to steps. I first explain what you need, what my rscript does, and how to deal with credentials. You save your script locally in a git repository (We want the code to run on computer in the cloud)

use r-lib/actions/setup-r (a functioning ubuntu container with R installed).

tell github to take our last version of the repo.

You create github actions by writing down the steps in a yaml file in a specific Github actions is a new product from github, you get 2000 minutes per account/month. Find all posts about scheduling an R script here Github actions details I found it quite difficult to make it work in one go. Github actions is completely scriptable and works quite well.

But in this case I will run the script on github actions. I will create a new post for many of the other ways on which you can run an R script on schedule. The use case is this: You have a script and it needs to run on a schedule (for instance every day). It creates a curve in ggplot2 and posts that picture to twitter. In this tutorial I have an R script that runs every day on github actions.
