A snippet of R showing how to access a CKAN portal via its API, in this case opendata.swiss

ckan-opendata-example.r

install.packages("ckanr")
library('ckanr')

# Initialise the CKAN library with a remote portal
ckanr_setup(url = "https://opendata.swiss")

# Run a search to get some data packages
x <- package_search(q = 'name:arbeitslosenquote', rows = 1)

# Note that on the Swiss server the titles are multilingual
x$results[[1]]$title$de

# Get the URL of the first resource in the first package
tsv_url <- x$results[[1]]$resources[[1]]$download_url

# Download the remote (Tab Separated Values) data file
# ..and parse it in one step
raw_data <- read.csv(tsv_url, header=T, sep="\t")

# Draw a simple plot of the first and second column
plot(raw_data[,2], raw_data[,1], type="b")
