Accessing open data with style
⛶ Open fullscreen
The image above is a screenshot of an example R program running on RStudio Cloud. This uses the R library for CKAN to connect to opendata.swiss, data.stadt-zuerich.ch and other data portals which support the CKAN API. Why is this important?
- You are using the latest version of the dataset;
- Your program is showing each step of the data extraction process;
- If there are notable changes to the data, including errors or improvements, they will soon be picked up;
- Additional metadata that is not part of the dataset content can be useful to your process.
Try copying and adapting the code for yourself:
library('ckanr') # Initialise the CKAN library with a remote portal ckanr_setup(url = "https://data.stadt-zuerich.ch/") # Run a search to get a list of datasets datasearch <- package_search(q = 'frauen', rows=20)$results # Take the first result available opendataset = datasearch[] print(opendataset$title) print(opendataset$resources[]$name) # Get the dataset contents through the first resource URL csv_url = opendataset$resources[]$url # Read as CSV for further processing, visualisation.. csvdata <- read.csv(csv_url, header=T, sep=",")
