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")
