First, please use the citNet_dataPrep.R to generate data files needed for simulations.
Then use null_model.cpp to run the null model.
Some code for further analyses can be found in citNet_main.R.
The data we provide here are obtained through American Physical Society. After some processing, we store the data in three files: doiYear.RData, Barabasi_cite.RData, and citationBara.csv.
Here we upload a dataset of a relatively small discipline in order to help readers replicate our analysis, and we note that the effects reported in our paper might not be present if the scientific community is not large enough.
