rcanvas is a bouquet of functions to query your institution’s instance of the Canvas LMS.

rcanvas is not on CRAN, but can be installed via:

devtools::install_github("daranzolin/rcanvas")
library(rcanvas)

Some prep work is required before use. You must first safely stash your Canvas API token into your operating system’s keyring. This only needs to be done once.

To obtain the Canvas API token follow this trail in Canvas:

Canvas -> Account -> Settings -> Approved Integrations -> Add new token

You then need to run the following once in the R console:

set_canvas_token("YOUR_TOKEN_HERE")

Do not save your token or the code above in an .R file because it could compromise the security of your token.

Each time you run load the rcanvas library you need to set your domain like this:

set_canvas_domain("https://canvas.yourdomain.edu")
