Dispersion / adjusted frequency resources


R scripts to compute measures of dispersion and adjusted frequencies

R scripts

Script 1: dispersions1
Script 2: dispersions2
Enter this into R to make the function from the first script (and change the "1" to "2" for the second one):
source("http://www.linguistics.ucsb.edu/faculty/stgries/research/dispersion/_dispersions1.r")¶
Then you can call the function as described in the article.
