[R] A good DBMS for R?

[TyagiAnupam@aol.com]

<PRE>I am looking for suggestions for a good Database Management System to use 
with R.  The main use of this will be to format, query and make subsets of 
large datafiles for use in R.  I recall reading a comparative write-up either 
in the newsletter, in the mails or someone's webpage last summer, but cant 
seem to find it now.  I will be thankful if someone can help in locating such 
a document.  For the DBMS it will be nice if it is a good database system to 
learn independent of its integration with R. My preference will be something 
that also works under Linux and has a user-friendly interface.
