In chopin: Spatial Parallel Computing by Hierarchical Data Partitioning

Split grid list to a nested list of row-wise data frames

Description

Split grid list to a nested list of row-wise data frames

Usage

par_split_list(gridlist)

Arguments

gridlist

list. Output of par_pad_grid or par_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.

Value

A nested list of data frames or WKT strings.
