No interpolated results returned with the argument "fill_gaps==TRUE"

[PenguinSmith]

Hi,
The argument fill_gaps of povcalnet() is described as "logical: 'TRUE' will interpolate / extrapolate values when surveys are not available for a specific year." However, no interpolated result (poverty headcount/gini etc) is returned when this argument is TRUE. I requested data for all countries with fill_gaps==TRUE and got a returned dataframe with a variable isinterpolated. It turns out that isinterpolated is always 0 (indicates no interpolation), and the total amount of data is equal to that with fill_gaps==FALSE.

Is there a mistake in this function or something I have misunderstood?
Really need the interpolated data (or methodology). Thanks in advance.

Hi @PenguinSmith

Thanks for your patience on this. I was on leave, and just saw your message. The fill_gaps argument seems to be working fine.
Running df <- povcalnet(fill_gaps = FALSE) returns a 1962 observations, while df <- povcalnet(fill_gaps = TRUE) returns 2671 observations.

The isinterpolated variable is misleading, and its behavior will be updated in a future release. Please ignore it for now.

Hope that helps!
