[R list package] R package "list" question

[Kosuke Imai]

Hi Meredith,

   Sorry for the poor documentation.  I'm ccing my coauthor who should 
be able to correct me if I'm wrong on this and update the documentation 
accordingly, but something like the following (an example of 3 control 
items) should work:

ictreg(cbind(control.y1, control.y2, control.y3, treat.y) ~ x1 + x2, 
data = data)
