This function can be used to read a portfolio object that was previously
written to disk via write_portfolio() back into R as an sf object.
It should specifically be directed against a GeoPackage which was the output
of write_portfolio(), otherwise the function is very likely to fail.
All available indicators will be read back into R as nested list columns
reflecting the output once calc_indicators() has been called.
Arguments
- file
A character vector pointing to a GeoPackage that has been previously written to disk via
write_portfolio()- ...
Additional arguments supplied to
st_read()
Value
An sf object object with nested list columns for every indicator table found in the GeoPackage source file.
Details
Important Note
Portfolio-wide attributes that were specified via init_portfolio() will
not be reconstructed. The reason is that users most likely exported to a
GeoPackage in order to share their data, thus the file is very likely to be
opened on a different machine / in a different working directory. Users can
simply apply init_portfolio() on the object to re-set these attributes.
