alternatively to mirecords, you can download fasta-formatted human (and
other) mirs and targets from mirbase at sanger [1], and importing fasta
to r should be an easy task for you.  alternatively, there are database
dumps available. 

i don't know of an r/bioc package targetted specifically at a mirna
database;  it's possible that the data are not available for
programmatic access otherwise than through a bulk download (or html
parsing, if you prefer...)
