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