Installation

First, you have to install the rjson package for R. Under Debian or Ubuntu, this can be done by installing the r-cran-rjson package. Otherwise, you can install it by issuing the following in R: install.packages("rjson").

Then, clone the git repository and, from the upper-level directory, issue this command in a shell:

R CMD INSTALL dbnomics-connector.R

This will install the package in some path accessible to R.

Then, in every session where you want to use the package, issue the following in R:

library(DBnomics)

Retrieving a series as a timeseries object

If you know the id of a series, you can get it as a ts (R timeseries) object with the get.series.as.ts function.

For example:

get.series.as.ts("eurostat", "5369a7fe9f8f083631ab1b2a")

Lower lever interface

For each accessible method of the web API there is a R counterpart. It returns the JSON object as an R list.

The methods are:

• retrieving all categories: list.categories(db)
• retrieving a specific category: get.category(db, category.id)
• retrieving all series of a category: list.series(db, category.id)
• retrieving a specific series: get.series(db, series.id)
