Hi there, I'm trying to connect in an Oracle database. I am able to do it with Java, but when trying this code in R: library(DBI) library(RJDBC) drv = JDBC("oracle.jdbc.driver.OracleDriver", "C:\\Documents and Settings\\rodri\\workspace\\AtlasQueryingTest\\lib\\ojdbc14.jar", identifier.quote="`") con=dbConnect(drv,url="jdbc:oracle:thin:@apu.ebi.ac.uk:1521:AEDWT",uid="rodri", pwd="rodri") The JDBC() call seems to work fine but dbConnect() returns: Error in .verify.JDBC.result(jc, "Unable to connect JDBC to ", url) : Unable to connect JDBC to jdbc:oracle:thin:@apu.ebi.ac.uk:1521:AEDWT (invalid arguments in call) I guess it should be a problem with the driver, because the other parameters are simple and work ok in Java-equivalent code I've tried to find info in the forums, and i've found the same question but with no response My environment is -R 2.7.0 With -RJDBC -DBI -rJava -Java 1.6.0_03 -ojdbc14.jar with OracleDriver (working fine in java code) -Windows XP Thanks in advance!
