Galvanising the Open Access Community: A Study on the Impact of Plan S - Data and Code

This repository contains the datasets and code underpinning Chapter 3 "Counterfactual Impact Evaluation of Plan S" of the report "Galvanising the Open Access Community: A Study on the Impact of Plan S" commissioned by the cOAlition S to scidecode science consulting.

Two categories of files are part of this repository:

1. Datasets 

The 21 CSV source files contain the subsets of publications funded by the funding agencies that are part of this study. These files have been provided by OA.Works, with whom scidecode has collaborated for the data collection process. Data sources and collection and processing workflows applied by OA.Works are described on their website and specifically at https://about.oa.report/docs/data.

The file "plan_s.dta" is the aggregated data file stored in the format ".dta", which can be accessed with STATA by default or with plenty of programming languages using the respective packages, e.g., R or Python. 

2. Code files

The associated code files that have been used to process the data files are:

- data_prep_and_analysis_script.do - coef_plots_script.R

The first file has been used to process the CSV data files above for data preparation and analysis purposes. Here, data aggregation and data preprocessing is executed.  Furthermore, all statistical regressions for the ounterfactual impact evaluation are listed in this code file. The second code file "coef_plots_script.R" uses the computed results of the counterfactual impact evaluation to create the final graphic plots using the ggplot2 package.

The first ".do" file has to be run in STATA, the second one (".R") requires the use of an integrated development environment for R.
