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.
