Fixed bug in makeFrontier(). Previous Mahalanobis frontiers are off by a small factor, mistakenly appearing nonmonotonic on occasion.
Fixed bug in estimateEffects(). Previous estimates on Mahalanobis frontiers use the wrong weights.
Help files in generateDataset(), plotEstimates(), and plotFrontier() improved.
Added model dependence intervals to plotEstimates() plots.
Added new function plotMeans() to plot means of covariates along the frontier.
Added option to include covariates not matched on in the data output by makeFrontier().
Added option to set.seed() for model dependence intervals.
First version released on CRAN.
This is a beta release with many changes to come.
