The first linguistic study demonstrating dynamic visualisation of language change with motion charts is Hilpert (2011). Martin Hilpert also provides more resources on linguistic motion charts here.
The R codes were created in 2014 for preparing the paper. The following R packages are required (and were used for the codes in 2014, which still run as per March 2019):
The R codes files begin with numbers, reflecting the order along which the codes should be run. The reshape package is required to run codes in 1-script-create-input-data-raw.R. The input data for this script are two matrix tables for the co-occurrence frequencies of infinitival collocates with will (will_INF.txt) and going to (go_INF.txt) across the 20 periods of COHA (Davies 2012). The output file for the first script is input_data_raw.txt.
Given the input_data_raw.txt and coha_size.txt, the second script (2-script-create-motion-chart-input-data.R) performs normalisation of the token frequency per million words of the infinitives with will and going to. This process generates the relevant input data (i.e. input_data_futurate.txt) for creating the static motion chart plot for the paper (with 3-script-create-motion-chart-plot.R) and the dynamic motion chart that can be previewed in web browser (with 4-script-motion-chart-dynamic.R), providing that Adobe Flash Player plug-in has been installed on the browser. In script 4, the googleVis package is required.
Script no. 5 (5-tidyverse-codes.R) captures scripts 1 to 4 with tidyverse packages.
