An easily accessible Graphical User Interface for generating Haplin syntax is under development, and a preliminary versjon is available at haplin.fhi.no, thanks to Nguyễn Trung Trực. The syntax generator helps setting up Haplin commands which can be cut and pasted into your own R window. It includes some (but not all) of the features currently available in Haplin.

NOTE: Unfortunately, the GUI web page is temporarily unavailable.
