JDBC DB access in R

The J is for Java (I presume, you did't actually say), and R is written in
C.  So `all' you need to do is to call a Java wrapper from R and call JDBC
from that.  I believe it has been done via RSJava.

But if all you want to do is to retrieve a dataframe, isn't this rather 
hard work?

Hello, i see packages referencing using ODBC access to databases via R, are
there any packages that use JDBC to submit SQL to a database and return into
a data frame?
