About this document
This document is a R notebook, dynamically created from the numbers extracted on the project. It lists all datasets published for the project, providing basic numbers, figures and a quick summary, and serves as a test case to make sure that all the required data is present and roughly consistent with requirements. All plots and tables are computed from the actual data as provided in the downloads.
To re-execute the document, simply start a R session, load rmarkdown
and render
the page with the project ID as a parameter:
require('rmarkdown')
render("datasets_report.Rmarkdown", params = list(project_id = "technology.epf"), output_format="html_document")
This website uses the blogdown R package, which provides a different output_format for the hugo framework.

Downloads
All data is retrieved from Alambic, an open-source framework for development data extraction and processing.
This project’s analysis page can be found on the Alambic instance for the Eclipse forge, at https://eclipse.alambic.io/projects/technology.epf.
Downloads are composed of gzip’d CSV and JSON files. CSV files always have a header to name the fields, which makes it easy to import in analysis software like R:
data <- read.csv(file='myfile.csv', header=T)
names(data)
