widths {fmtr} | R Documentation |
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
x |
A data frame or tibble |
value |
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.
A named list of widths. The widths must be positive integers greater than zero.
