Creation

Functions to convert objects into the two post classes provided: post_array (which inherits {stars} functionality) and post_table (which inherits {cubble} functionality).

as_post_array(): Create a post_array object

as_post_table(): Create a post_table object

With dplyr

post supports most of the {dplyr} verbs supported by {cubble} and {stars} except for those when the result would not be a post object anymore e.g. dplyr::summarise, dplyr::pull.
