Take a data frame with several designated variables to be used as axes in an
alluvial diagram, and reshape the data frame so that the axis variable names
constitute a new factor variable and their values comprise another. Other
variables' values will be repeated, and a row-grouping variable can be
introduced. This function invokes gather.
to_lodes(data, key = "x", value = "stratum", id = "alluvium", axes)
| data | Data frame. |
|---|---|
| key, value, id | Character; names given to the axis (variable), stratum (value), and alluvium (identifying) variables. |
| axes | Numeric or character vector; which variables to use as axes. |
