[R] SQL and R

[akshay kulkarni]

dear Members,
                            I have recently started studying SQL and MySQL. My question is, what exactly is SQL used for? That is, whatever can be done by SQL, like subsetting and filtering of data sets, can also be done by R. What's, then, the advantage of SQL?  It is OK if you tag this question as offtopic, but I could'nt find any info on the web. Can you please refer me to some online resources that shed some light on this? Finally, how does SQL complement R? Are both dependent?

THanking you,
Yours sincerely,
AKSHAY M KULKARNI
