write map data for Mondrian
The function outputs a SpatialPolygonsDataFrame object to be used by Mondrian
sp2Mondrian(SP, file, new_format=TRUE)
SP |
a SpatialPolygonsDataFrame object |
file |
file where output is written |
new_format |
default TRUE, creates a text data file and a separate map file; the old format put both data sets in a single file - the map file is named by inserting "MAP\_" into the file= argument after the rightmost directory separator (if any) |
At this release, the function writes out a text file with both data and polygon(s) identified as belonging to each row of data.
