Pxweb Download _VERIFIED

There are two ways of using the pxweb R package toaccess data, either interactively or using the core functions. To accessdata, two parts are needed, an URL to the data table in the API and aquery specifying what data is of interest.

Although, if the pxweb is installed again, it willoverwrite the old API catalogue. So the easiest way is to add a PXWEBAPI to the global catalogue. To do this, do a pull request at the pxwebGitHub page here.

To download data, we need both the URL to the table and a queryspecifying what parts of the table are of interest. An URL to a table isan URL that will return a metadata object if not a query is supplied.Creating a query can be done in three main ways. The first and moststraightforward approach is to use pxweb_interactive() toexplore the table URL and create a query interactively.

Some return formats return files. Then, these responses are stored inthe R tempdir() folded, and the file paths are returned bypxweb_get(). Currently, px andsdmx formats can be downloaded as files, but file an issueif you need other response formats.

Under the hood, the pxweb package uses the pxweb_get() function to access data from the PXWEB API. It also keeps track of the API's time limits and splits big queries into optimal downloadable chunks. If we use pxweb_get() without a query, the function either returns a PXWEB LEVELS object or a PXWEB METADATA object. What is returned depends on if the URL points to a table in the API or not. Here is an example of a PXWEB LEVELS object.

To download data, we need both the URL to the table and a query specifying what parts of the table are of interest. An URL to a table is an URL that will return a metadata object if not a query is supplied. Creating a query can be done in three main ways. The first and most straightforward approach is to use pxweb_interactive() to explore the table URL and create a query interactively.

We can validate the query against the metadata object to asses that we can use the query. This validation is done automatically when the data is fetched with pxweb_get() but can also be done manually.
