[R-SIG-Finance] Rblpapi connection issue

[John Laing]

I think you may have misinterpreted. You _should_ call blpConnect, and you
only need to do it once. You don't need to call blpAuthenticate. A very
short script might look like this:

require(Rblpapi)
blpConnect()
bdp("USDCAD Curncy","PX_LAST")
