Use this function to modify the descriptions in a data-dictionary,
using syntax along the same lines as dplyr::mutate().
stw_mutate_dict(...) # S3 method for default stw_mutate_dict(...) # S3 method for stw_dict stw_mutate_dict(dict, ...) # S3 method for stw_meta stw_mutate_dict(meta, ...) # S3 method for stw_dataset stw_mutate_dict(dataset, ...)
| ... | Name-value pairs of expressions |
|---|---|
| dict | Object with S3 class |
| meta | Object with S3 class |
| dataset | Object with S3 class |
modified copy of dict or meta
You can send a dictionary (stw_dict) object, a metadata (stw_meta)
object, or dataset object (stw_dataset) and get back an object of
the same class. In other words, if you call this function using a
stw_meta object, it will modify the dict within the object,
then return a modified copy of thestw_meta object.
