This function makes it easy to get the note attribute from either an
individual vector or a data frame. NOTE: it is not possible to set or modify
the note attribute with this function.
Arguments
- x
A vector object, the name of a column in a data.frame, or an
an actual data.frame object.
- data
A data.frame or tibble object. This should only be specified
when x is only the name of a column in a data.frame.
Value
If x is a variable or vector, a string containing the "note"
attribute, if one is present, is returned. If x is a data.frame then a
named vector with the "note" attribute from each variable is returned.
