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...
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-
