Extractor function for the name of the family function of an object in the VGAM package.
familyname(object, ...)
familyname.vlm(object, all = FALSE, ...)A character string or vector.
Some VGAM object, for example, having
class vglmff-class.
If all = TRUE then all of the vfamily slot is returned;
this contains subclasses the object might have.
The default is the return the first value only.
Other possible arguments for the future.
Currently VGAM implements over 150 family functions.
This function returns the name of the function assigned
to the family argument, for modelling
functions such as vglm
and vgam.
Sometimes a slightly different answer is returned, e.g.,
propodds really calls cumulative
with some arguments set, hence the output returned by
this function is "cumulative" (note that one day
this might change, however).
vglmff-class,
vglm-class.
pneumo <- transform(pneumo, let = log(exposure.time))
fit1 <- vglm(cbind(normal, mild, severe) ~ let,
cumulative(parallel = TRUE, reverse = TRUE), data = pneumo)
familyname(fit1)
familyname(fit1, all = TRUE)
familyname(propodds()) # "cumulative"
