System Information

R Versions Available to RStudio Connect

This recipe compares your local R version against the R installations available on your RStudio Connect server. It uses the GET /server_settings/r endpoint to obtain the R installations available to RStudio Connect.

1. Obtain the server URL and API Key from environment variables
2. Obtain your local R version using R.version
3. Call the "Get R Installation Info" endpoint. See the API Documentation for more information.
4. Parse the response using httr::content.
5. Check the response for the local R version. If it is not listed, the RStudio Connect server does not contain the local R version.

library(httr)

# The connectServer URL must have a trailing slash.
connectServer <- Sys.getenv("CONNECT_SERVER")
connectAPIKey <- Sys.getenv("CONNECT_API_KEY")

myRVersion <- paste(R.version$major, R.version$minor, sep = ".")
resp <- GET(
  paste0(connectServer, "__api__/v1/server_settings/r"),
  add_headers(Authorization = paste("Key", connectAPIKey))
)
payload <- content(resp, as="parsed")
if (myRVersion %in% unlist(payload)) {
  print("The local R version was found on the RStudio Connect server")
} else {
  print(paste("Cannot find R version", myRVersion,"on the RStudio Connect server"))
}
