I came across the package 'ineq' that computes a variety of inequality measures (e.g. gini, theil etc). I want to compute the Theil index (racial segregation) and decompose the total into sub-components (by geog levels). I think the package doesn't report the decomposition (correct me if I'm wrong). Just wonder is that available elsewhere? K.

...package ?fields? is not available The package 'fields' *does* appear in the list of available packages at my local repository: http://cran.stat.sfu.ca/, and I've installed the dependencies ('spam').
