Makes a best guess at the design of a long-format data frame. Finds all columns that contain a single value per unit of analysis (between factors), all columns that contain the same values per unit of analysis (within factors), and all columns that differ over units of analysis (dv, continuous factors)
get_design_long(data, dv = "y", id = "id", plot = faux_options("plot"))
| data | the data frame (in long format) |
|---|---|
| dv | the column name that identifies the DV |
| id | the column name(s) that identify a unit of analysis |
| plot | whether to show a plot of the design |
the data frame in long format
