Dear All,

I would greatly appreciate a pointer regarding some problems I  am having with the "bar" function in RBloomberg. While, I have no problem with "tick" or "bdh" functions I cannot get the example under [http://www.findata.org/rbloomberg/examples/bar.R] to run.

The example code:

conn <- blpConnect()
bar(conn, "RYA ID Equity", "TRADE", "2010-03-01 09:00:00.000", "2010-03-01 15:00:00.000", "60")

gives output:
> library(RBloomberg)
> conn <- blpConnect()
R version 2.11.1 (2010-05-31)
rJava Version 0.8-5 
RBloomberg Version 0.4-142 
Java environment initialized successfully.
Looking for most recent blpapi3.jar file...
Bloomberg API Version 
> bar(conn, "RYA ID Equity", "TRADE", "2010-03-01 09:00:00.000", "2010-03-01 15:00:00.000", "60")
Fehler in process.result(result, "first.column") :   Indizierung außerhalb der Grenzen


> bar(conn, "CO1 Comdty","PX_LAST", "2010-09-10 10:00:00.000","2010-09-10 10:01:00.000","1")
Fehler in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  :   com.bloomberglp.blpapi.InvalidConversionException: Cannot convert String  to Enumeration

while bdh(conn,"CO1 Comdty","PX_LAST","20100801","20100901") works fine

Any ideas in which direction I should search for errors?

Many Thanks
