write_portfolio() writes a processed biodiversity portfolio to disk.
Portfolio data will only be serialized to disk as a GeoPackage including
two tables: metadata and indicators. The metadata tables
includes, among other simple variables the geometries and a primary
key called assetid. The 'indicators' tables includes the foreign key
assetid, a column called indicator giving the name of the original
indicator as well as the standard indicator columns datetime, variable,
unit, and value. For convenience, use read_portfolio() to read
such a portfolio GeoPackage back into R.
portfolio_long() transforms a portfolio to long-format, potentially
dropping geometries in the process.
portfolio_wide() transforms a portfolio to wide-format, potentially
dropping geometries in the process.
write_portfolio(x, dsn, ...)read_portfolio(src, ...)
portfolio_long(x, indicators = NULL, drop_geoms = FALSE)
portfolio_wide(x, indicators = NULL, drop_geoms = FALSE)
write_portfolio() returns dsn, invisibly.
read_portfolio() returns an sf object object with nested list
columns for every indicator found in the GeoPackage source file.
portfolio_long() returns the portfolio object in long-format.
portfolio_wide() returns the portfolio object in wide-format.
A portfolio object processed with mapme.biodiversity.
A file path for the output file (must end with gpkg).
Additional arguments supplied to write_sf() or read_sf()
A character vector pointing to a GeoPackage that has been
previously written to disk via write_portfolio()
If NULL (the default), all indicator columns will be detected and transformed automatically. If a character vector is supplied, only those indicators will be transformed.
A logical, indicating if geometries should be dropped.
