This dataframe can be converted into a repgrid object via importDataframe().
The long format has this name because it has few columns and many rows. It is a common format
in data analytics. Here, each row contains a different element-construct combination and the corresponding rating
value. The format looks like this:
Details
element | left_pole | right_pole | rating | preferred_pole | rmin | rmax |
element 1 | left pole 1 | right pole 1 | 5 | left | 1 | 5 |
element_2 | left pole 1 | right pole 1 | 3 | left | 1 | 5 |
element_3 | left pole 1 | right pole 1 | 1 | left | 1 | 5 |
The columns element, left_pole, right_pole, and rating are mandatory, the columns preferred_pole, rmin,
and rmax are optional. rmin and rmax contain the min and max of the rating scale. Alternatively, you may
pass rmin and rmax as arguments in the function call.
