bdh: problem with int.as.double

[mgartner6]

There seems to be a problem in bdh() since the implementation of the function argument int.as.double. Please try the following:

library(Rblpapi)
blpConnect()
bdh('SPX Index', 'PX_VOLUME', start.date = Sys.Date()-365*10, int.as.double = FALSE)

This ends up in the following error:

Error in bdh_Impl(con, securities, fields, start.date, end.date, options,  : 
  Attempt to access value of element 'PX_VOLUME'(type: 'Float64') as 'Int32' type.

But, if I set int.as.double = TRUE everything works fine.

The error seems to be dependent on the required time horizon, if I just query one year instead of 10 years of historic data and set start.date = Sys.Date()-365 instead of start.date = Sys.Date()-365*10 the function works fine with both, int.as.double = TRUE and int.as.double = FALSE.

However, for me the best solution is to set the default of int.as.double to TRUE.

Could you advise on this?

Short answer: the int.as.double argument was added to solve exactly the problem you are experiencing. The best thing to do is set it to TRUE.
