Split grid list to a nested list of row-wise data frames
Arguments
- gridlist
list. Output of
par_pad_gridorpar_pad_balanced
Details
If the input is a data frame, the function will return a list of
two data frames: original and padded. If the input is a WKT vector,
the function will return a list of two WKT strings: original and padded.
