[Rsiena-help] helpt with selecting actors

[maarten van zalk]

To whom it may concern,

I am trying to select actors in RSiena on the mac but get strange  
errors that I cannot seem to solve. It seems that the cohort variable  
has NULL but it actually has 2083 actors, of which around 1200 have  
the value 1.

Has anyone had this problem before?

Kind regards,

Maarten van Zalk
