I programmed in SAS for 3 years and would like to switch to a not so costly
Hence I started to evaluate R, and my first test look promising.
However I have some question:
1. Is it possible to query R files by SQL internally on data frames (not on
a database) and how is the syntax (I have the RODBC package installed).
I would like to extract year, Quarter, week, from a date column in a data
frame (see attachment). After this I want to attach the column to the
original data frame.
How do I do this in R?
