Juan,
something weird with your install / help, below what I get (R 2.15.0)
blpConnect {RBloomberg}R Documentation
Open or shut a connection to Bloomberg
Description
The function blpConnect returns a connection object to one of
the Bloomberg interfaces. Currently, only the Java Version 3 API is
supported.
Usage
blpConnect(iface = "Java", log.level = "warning", blpapi.jar.file = NULL,
throw.ticker.errors = TRUE, jvm.params = NULL, verbose = TRUE)
blpConnect.Java(log.level, blpapi.jar.file, throw.ticker.errors, jvm.params,
verbose)
blpDisconnect(conn)
Arguments
iface
character. Which Bloomberg interface? (only "Java" currently supported).
log.level
character. Level of logs to be generated by Java. Acceptable values: warning,
info, fine, finest.
blpapi.jar.file
character. Location of the Bloomberg API JAR file. If NULL (default), the
function looks in usual locations.
throw.ticker.errors
logical. Should errors be thrown for invalid tickers?
jvm.params = NULL
Parameters passed to the Java Virtual Machine
verbose = TRUE
logical. Should output be written to the console on connection?
conn
Connection object
>>> Also, R tells you he cannot uses the arguments:
(na.action = "na", periodicity = "daily")
so you might (for next time) to look at the code of your function, you can look
at the code in a majority of R function is just type it in the console without
the brackets
You can see the function argument & no "na.action" or "periodicity" (which are
pretty weird arguments for a connection function anyway!)
> blpConnect
function (iface = "Java", log.level = "warning", blpapi.jar.file = NULL,
throw.ticker.errors = TRUE, jvm.params = NULL, verbose = TRUE)
{
valid.interfaces <- c("Java")
future.interfaces <- c("C")
if (iface %in% future.interfaces) {
stop(paste("Requested interface", iface, "is not yet implemented."))
}
if (!(iface %in% valid.interfaces)) {
msg <- paste("Requsted interface", iface, "is not valid! Valid
interfaces are ",
do.call("paste", as.list(valid.interfaces)))
stop(msg)
}
fn.name <- paste("blpConnect", iface, sep = ".")
fn.call <- call(fn.name, log.level, blpapi.jar.file, throw.ticker.errors,
jvm.params, verbose)
eval(fn.call)
}
<environment: namespace:RBloomberg>
May be a full re-install?
Good luck
HTH,
Julien

Thanks again
When I run
blpConnect(iface="Java") it worked
But when I run blpConnect(iface="Java", timeout=12000, show.days="week",
na.action="na", periodicity="daily"), I got an error message
> conn=blpConnect(iface="Java",na.action="na",periodicity="daily")

Looking for most recent blpapi3.jar file...
Adding C:\blp\API\APIv3\JavaAPI\v3.4.6.6\lib\blpapi3.jar to Java classpath
Bloomberg API Version 3.4.6.6
I also found that website, but in that website it refers to iface=COM, which
confuses me
Open or shut a connection to Bloomberg
Description
The function blpConnect returns a connection object to one of the Bloomberg
interfaces. Currently, only the COM Desktop API is supported.
Usage
blpConnect(iface="COM", timeout=12000, show.days="week",
na.action="na", periodicity="daily")
blpDisconnect(conn)
Finally, you were right, I didnt load the library before y type help. Help
function took me to
http://127.0.0.1:22382/library/RBloomberg/html/blpConnect.html
The thing that confuses me now is how to set up blpConnect to stablish the
conection and also set up the parameters
na.action = "na", periodicity = "daily"
that I need for my work
Thanks a lot
JJ

Juan,
No problem, I thik my point is that the blpConnect function does accept only
iface="Java" as argument, hhence trying iface="COM" you get the error msge
Weird the help() does not work - did you have the RBloomberg package loaded
when trying the help(blpConnect)?
May be you did not install the help file alongside R? If so I would recomment
to do so.
I found this which might help, google is your friend ;-):

Thnkx very much. Actually the full code is this
blpConnect(iface="COM",
na.action="na", periodicity="daily")
I think this is the proper way to use the function (I am a R beginner), thats
why I used it
When I type help(blpConnect) I get this:
No documentation for blpConnect in specified packages and libraries:
you could try ??blpConnect
I followed the manual instructions and installed Java Version 3 API,
rJava package and I also downloaded Jave from the Java website.
Thanks again
JJ

Hi,
when I type help(blpConnect) in R, I read this:
"
Arguments
iface
character. Which Bloomberg interface? (only "Java" currently supported).
"
why do you try to give the "COM" value to iface argument?
after the :
"conn <- blpConnect()" you are connected as far as I know?
If I said something stupid, sure the package owner will contradict me
Rgds,

Dear All,
In the first place I would like to thank you for your contribution to R.
I am having this problem with Rbloomberg.
I followed the manual and downloaded the API from bloomberg. However, when I run
conn=blpConnect(iface="COM") I got the error message below . ¿do you know why
this might happen?
Thanks very much
