similar to: Retrieving data through bbg or excel, what is faster?

I am having a puzzling problem with bloomberg connection. When i  run from R prompt some code that has .... library(Rbbg) conn <- blpConnect(throw.ticker.errors = FALSE) print("connected") ... I establish connection every time and then proceed to get data when i run this code from R prompt. However, when i run this from a batch script, i get the following error output from Rbbg:

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

Dear R Users, Anyone know of a version of Rbbg compiled for R 2.15.2 . The current version does not appear to work with 2.15.2 > install.packages("Rbbg", repos = "http://r.findata.org") Installing package(s) into ?C:/Users/t_uzu_000/Documents/R/win-library/2.15? (as ?lib? is unspecified) Warning: unable to access index for repository http://r.findata.org/src/contrib

for the moment, I'm using: .onAttach <- function(libname, pkgname) { .bbg.db.conn <<- dbConnect(dbDriver("PostgreSQL"), user="blah","blah") } .onUnload <- function(libpath) { dbDisconnect(.bbg.db.conn) } which results in a hidden global variable in the global environment. I would prefer to make the assignment only in the package namespace.

A criticism of your suggestion is that it is not backwards compatible. Does that matter? I don't know, but probably not. The X11 version of the viewer does what you suggest.

About the decisions: Actually, the same way dataedittext modifies the text colour not only of data, but also of row and column names, and dataedituser modifies the colour of all the borders, I think dataeditbg should modify the background of all the window, at least that "inside" those borders. Otherwise, any other option for the background colour on row and column headers would allow

Hi everyone, I am trying to insert a row in sqlite table with my own unique id. I want to create unique id using sqlite internal function last_insert_rowid() which returns the next max rowid of the table which is always unique. I tested this using sqlite and it works fine but when i run the same query using RSQlite from r prompt, my query doesn't create new unique id. last_insert_rowid()
