ismissing method is missing

Hello! I have a dataset (class) A with some missing data (NaN, '' and such.) According to the dataset class description there is supposed to be a method called ismissing disigned to find these rows. Unfortunately I get:

    I = ismissing(A)
  Undefined function 'ismissing' for input arguments of type
  'dataset'.

Has anybody had this problem before? It seems most of the other methods listed in http://www.mathworks.se/help/stats/datasetclass.html works.

Weird! Thankful for any suggestions.

does the following work?

A = dataset;
ismissing(A)

I have the exact same problem. I get "Undefined function or variable 'ismissing'." I use version R2016a, Statistics and Machine Learning Toolbox Version 10.2 Anyone have a solution?
