generate(x, n_along = 5, n_by = 1, n_draw = 25, ...)Arguments
- x
Object of class
"bage_prior"- n_along
Number of elements of 'along' dimension. Default is
20.- n_by
Number of combinations of 'by' variables. Default is
1.- n_draw
Number of draws. Default is
25.- ...
Unused. Included for generic consistency only.
- n_element
Number of elements in term, in priors that do not distinguish 'along' and 'by' dimensions. Default is
20.
Value
A tibble
Details
Some priors distinguish between 'along' and 'by'
dimensions, while others do not: see priors
for a complete list. Arguments n_along and n_by
are used with priors that make the distinction,
and argument n_element is used with priors that do not.
