[Rsiena-help] coding missings

[Huisman, Chip]

Dear all,
 
I get the following error message:
 
 
Error in sienaNet(array(c(friend.data.w1, friend.data.w2), dim = c(962,  : 
  entries in networks must be 0, 1, 10 or 11

I use 9 for missings and 10 for structural sero's. 
 
and I use the following script to indicate the missings:
friend.data.w1[friend.data.w1 %in% c(9)] <- NA
friend.data.w2[friend.data.w2 %in% c(9)] <- NA
 
what am I doing wrong here?
 
best wishes,
 
Chip
