portfolio {mapme.biodiversity}

Portfolio methods

Description

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.

Usage

write_portfolio(x, dsn, ...)

read_portfolio(src, ...)

portfolio_long(x, indicators = NULL, drop_geoms = FALSE)

portfolio_wide(x, indicators = NULL, drop_geoms = FALSE)

Arguments

x

A portfolio object processed with mapme.biodiversity.

dsn

A file path for the output file (must end with gpkg).

...

Additional arguments supplied to write_sf() or read_sf()

src

A character vector pointing to a GeoPackage that has been previously written to disk via write_portfolio()

indicators

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.

drop_geoms

A logical, indicating if geometries should be dropped.

Value

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.
