Version 1.0 of the R package "frontier" released
...ications have proven its reliability. Therefore, I have called the
latest version of this package "1.0." This version is almost identical
to the previous versions but it includes citation information and the
argument "farrell" of efficiencies.frontier() has been renamed as
"minusU" and the argument "farrell" of summary.frontier() has been
renamed as "effMinusU", because the term "farrell" was misleading in
some cases. The argument "farrell" can still be used for maintaining
backward-compatibility.
