Installation and Authentication in R

Once you created an free account you can find your authentification token in the settings of your account on the Quandl Homepage. You can verify that you are a registered user directly in R with the Quandl.api_key() function from R package Quandl.

Installing the R package Quandl if not installed already,

> install.packages("Quandl")

else load the package.

> library("Quandl")
> Quandl.api_key("YourAPItoken")
