[R-SIG-Finance] sudden problem with RBloomberg

[Ana Nelson]

Sergey,

Please read this before you post to this list again:
http://www.catb.org/~esr/faqs/smart-questions.html

Please try adding blpDisconnect(conn) as below. And please check the
log file for error messages as I asked you to in my previous email.


conn <- blpConnect(show.days="week", na.action="previous.days",
periodicity="daily")
bldata <- blpGetData(conn, .tickers, "PX_LAST", start=start.date,
end=end.date, retval="zoo")
blpDisconnect(conn)

conn <- blpConnect(show.days="trading"
, na.action="previous.days",
periodicity="daily")


Regards,
Ana
