[R] R-question

Hello Colleagues,
I programmed in SAS for 3 years and would like to switch to a not so costly
software product.

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?
