A generic function that extracts the response/dependent variable from objects.
depvar(object, ...)An object that has some response/dependent variable.
Other arguments fed into the specific methods function of
the model.
In particular, sometimes type = c("lm", "lm2") is
available, in which case the first one is chosen if the
user does not input a value.
The latter value corresponds to argument form2, and
sometimes a response for that is optional.
The response/dependent variable, usually as a matrix or vector.
By default
this function is preferred to calling fit@y, say.
# NOT RUN {
pneumo <- transform(pneumo, let = log(exposure.time))
(fit <- vglm(cbind(normal, mild, severe) ~ let, propodds, data = pneumo))
fit@y # Sample proportions (not recommended)
depvar(fit) # Better than using fit@y; dependent variable (response)
weights(fit, type = "prior") # Number of observations
# }
