Changed IMF API Dataflow structure

[mitcda]

The IMF API Dataflow structure appears to have recently changed, causing the DataflowMethod function to return an empty data frame. Proposed changes reference the changed IMF Dataflow structure.

Hi @mitcda , do you mind to provide more detail about why you get an empty data framm so I can reproduce the problem. I can still use the CRAN version of package without any trouble at this time.

Hi @mingjerli, here's what happens when I run the DataflowMethod and CompactDataMethod functions from the IMFData package on CRAN.

> DataflowMethod()
data frame with 0 columns and 0 rows

And when I run CompactDataMethod with checkquery=TRUE, it returns the following error, which on tracing back, appears due to the DataflowMethod function returning an empty data frame.

> databaseID <- 'IFS'
> startdate='2001-01-01'
> enddate='2016-12-31'
> checkquery = FALSE
> queryfilter <- list(CL_FREQ="", CL_AREA_IFS="GR", CL_INDICATOR_IFS=c("NGDP_EUR","NGDP_XDC"))

> GR.NGDP.query <- CompactDataMethod(databaseID, queryfilter, startdate, enddate, checkquery=TRUE)
Error in CompactDataMethod(databaseID, queryfilter, startdate, enddate,  : 
  databaseID is not exist in API
