Update bdh.R Example

[csrvermaak]

The BDH() example for an options field doesn't work as per the manual:

>opt <- c("periodicityAdjustment"="MONTHLY")
>bdh("SPY US Equity", c("PX_LAST", "VOLUME"),  start.date=Sys.Date()-31*6, options=opt)

Error: Enumeration type could not be found for MONTHLY

The correct override name is opt <- c("periodicitySelection"="MONTHLY")

>opt <- c("periodicitySelection"="MONTHLY")
>bdh("SPY US Equity", c("PX_LAST", "VOLUME"),  start.date=Sys.Date()-31*6, options=opt)

       date PX_LAST    VOLUME
1  2015-10-16  203.27 114580052
2  2015-10-19  203.37  76523897

Thank you -- looks good. That is the problem of the lack of unit tests ...

Nice catch. I am so sure I tested this before putting into the examples section. Oh well.

(You did forget to run roxygenize() though.)
