The R package "frontier" is based on "FRONTIER 4.1" [1] but it has
some improvements [2]. The models that can be estimated by the R
package "frontier" are the same as the models that can be estimated by
"FRONTIER 4.1". These models are explained in the file "Front41.pdf"
that is included in the archive "FRONT41-xp1.zip", which is available
at [1]. If you have any further questions regarding the "frontier"
package, please use a forum at the package's R-Forge site [3].
