Unable to connect R to MonetDB (MonetDB.R)

问题:

I'm trying to start with the MonetDB.R package but I struggle to setup a connection (dbConnect). Here is a reproductible example

require(MonetDB.R)
drv <- dbDriver('MonetDB.R')
con <- dbConnect(drv, 'monetdb://localhost/demo')
## Process R aborted (core dumped) at Thu Dec 26 11:03:47 2013
## R: mapi.c:72: mapiConnect: Assertion `Rf_isInteger(port)' failed.

Is there any trick to fix this error ?

I'm using the developpement version of MonetDB (Database: MonetDB v11.18.0 (unreleased)) , the latest version of R (beta build, see sessionInfo below) and Arch Linux (64 bit, kernel 3.12.5-1)

The reported problems are known and fixed in version 0.8.3 (and above) of the connector, which is available from CRAN.
