Using Rblpapi via rpy2

Question

I can successfully use the Rblpapi from R:

> library("Rblpapi")
> conn <- blpConnect(host='myhost', port=18194)
> bds("SPX Index", "INDX_MEMBERS")

Member Ticker and Exchange Code

501 YHOO UW
502 YUM UN
503 ZBH UN
504 ZION UW

However, I can't use it from Python:

>>> from rpy2.robjects.packages import importr
>>> r = importr('Rblpapi') 
>>> r.blpConnect(host='myhost', port=18194)
>>> print r.bds('SPX Index', 'INDEX_MEMBERS') 
NULL

The blpconnect() call seems to work (errors are thrown if the service isn't available), but I'm at a loss on how to debug this further.

Answer 1

You've misspelled INDX_MEMBERS

print r.bds('SPX Index', 'INDX_MEMBERS')

works as expected

Answer 2

Why? Bloomberg gives you plenty of Python APIs ready-made .
