The descriptions function extracts all assigned description
attributes from a
data frame, and returns them in a named list. The function also
assigns description attributes from a named list.
descriptions(x) descriptions(x) <- value
| x | A data frame or tibble |
|---|---|
| value | A named list of description values. |
A named list of description values.
If descriptions are assigned to the "description"
attributes of the data frame
columns, the descriptions function will extract those values. The
function will return the description values in a named list,
where the names
correspond to the name of the column that the description was assigned to.
If a column does not have a description attribute assigned, that column
will not be included in the list.
When used on the receiving side of an assignment, the function will assign descriptions to a data frame. The description values should be in a named list, where each name corresponds to the name of the data frame column to assign values to.
