This is the first time Rscript behaves differently than interactive R .

It looks like Rscript loads your .Rprofile file on startup, which is located in ~/.Rprofile.  You could just add library(methods) to your .Rprofile file and it should fix the issue.

Youre problem is not related to Quandl (or finance). When you run Rscript, it does not automatically load all the same packages loaded by the interactive window. In particular, Rscript does not automatically load the methods package (which defines getClass), so the R interpreter cannot find the getClass function.

As far as I know, the solution is to manually load all the required packages, including methods. Perhaps someone wiser than me can suggest an easier solution.

Quandl.auth(token)                           

A <- Quandl("QUANDL/ARS",start_date="1990-01-01" )
