I need to set up different paths for my code depending on whether it is being run in windows or unix. I currently have it set up so that the user has to change a variable "Renvironment" before running, as below. 

Renvironment <- "windows"

if (Renvironment == "windows") {
  working_dir <- "windows_path..."
  function_library <- "windows_path..."
} else if (Renvironment == "unix") {
  working_dir <- "unix_path..."
  function_library <- "unix_path..."
}

I was wondering though whether there are default R environment variables that I can use instead to save the user having to remember to manually change the variable?

The command .Platform returns details of the platform. You can access the information about the operating system with 

.Platform$OS.type

This returns either "unix" or "windows".
