1. sqldf takes one sql argument whereas the above has two sql
arguments; however, the one argument may be a vector of sql commands.
 See ?sqldf and the examples on the sqldf home page
http://sqldf.googlecode.com

2. there is an error in the syntax of your update statement.  For
correct syntax see the sqlite site:

    http://sqlite.org/lang_update.html
