RJDBC doesn't load Oracle driver?
...tabase. I use the JDBC
driver that works fine elsewhere (use it in DBVizualizer). However, when i
try to load the driver,
drv<-JDBC("oracle.jdbc.driver.OracleDriver",
"/home/az05625/DBdrivers/ojdbc6.jar", identifier.quote="`")

> drv <- JDBC("jstels.jdbc.mdb.MDBDriver",
"/opt/DbVisualizer-7.1.1/jdbc/mdb/mdbdriver.jar")
Error in .jfindClass(as.character(driverClass)[1]) :
java.lang.NoClassDefFoundError: org/apache/log4j/PropertyConfigurator
As you see I have added the log4j with .jaddClassPath. What is wrong?

software today (June 2 2008), first deleting and then replacing old
versions of software.
The error is as follows:
Error in .jfindClass(as.character(driverClass)[1]) : class not found
This error is produced after running the following code ():

VAR with binary endogenous variables
Hi all! Does anyone know if a vector autoregression package is avaialable
that allows binary variables as part of the endogenous system? I'm looking
for something along the lines of what is implemented in "Dynamic Forecasts
of Qualitative Variables: A Qual VAR Model of US Recessions" by Michael
Dueker, 2003, Fed Reserve Bank of St. Louis. Another possibility is the
