Hello everyone,

 

using the VGAM package and the following code

 

library(VGAM)

bp1 <- vglm(cbind(daten$anzahl_b, daten$deckung_b) ~ ., binom2.rho,
data=daten1)

summary(bp1)

coef(bp1, matrix=TRUE)

 

produced this error message:

 

error in object$coefficients : $ operator not defined for this S4 class

 

I am bit confused because some day ago this error message did not show up
and everything was fine.

 

Thank you very much in advance for your help.

 

Best,

 

Martin
