Rename variables in a draws object.

rename_variables(.x, ...)

# S3 method for draws
rename_variables(.x, ...)



(draws) A draws object.


One or more expressions, separated by commas, indicating the variables to rename. The variable names can be unquoted (new_name = old_name) or quoted ("new_name" = "old_name"). For non-scalar variables, all elements can be renamed together ("new_name" = "old_name") or they can be renamed individually ("new_name[1]" = "old_name[1]").


Returns a draws object of the same format as .x, with variables renamed according to the expressions provided in ....
