R help - Mar 2010 - Troubles on retrieving rownames

Hi guys, I am using the blp() function from RBloomberg package which returns
a matrix of prices with the columns corresponding to the security name and
the columns to the date. When I have a look at the matrix I can see the
rownames (dates) on the left of the prices but when I call the rownames()
function it returns me a NULL value. It worked perfectly until I had to
reinstall the RBloomberg package. Here is my code:
(you need to be connected to bloomberg to run it):
conn <- blpConnect(na.action="na")
prices <- blp(conn, securirtyNames, "PX_LAST", startDate,
endDate)
> rownames(prices)
NULL

any idea of what it could be? What I don't understand is that I can see
those rownames on the console...

do 'str(prices)' so we can see the structure of the data.

Given that there appears to be no function named blp in the Index of  
the current version of RBloomberg,  I am not surprised that you get a  
null return from rownames() on an object created by it.

I'm guessing that you need to use blpGetData or blpReadFields or one  
of the other higher level functions. The package maintainers are at R-
