observationType function

observationType - Type of observations

Return the type of observations (single or multiple observers) represented in either a fitted distance function or Rdistance data frame.

observationType(x)

Arguments

• x: Either an estimated distance function, output by dfuncEstim, or an Rdistance nested data frame, output by RdistDf.

Returns

One of the following values: "single", "1given2", "2given1", or "both". If observation type has not been assigned, return is NULL.

Details

This function is a simple helper function. If x is an estimated distance object, it polls the obsType

attribute of the object's Rdistance data frame. If x is an Rdistance nested data frame, it polls the obsType attribute.
