\begin{Description}\relax
\code{eapply} applies \code{FUN} to the named values from an
environment and returns the results as a list. The user can request
that all named objects are used (normally names that begin with a
dot are not). The output is not sorted and no parent environments are
searched.

\begin{verbatim}
eapply(env, FUN, ..., all.names = FALSE)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{env}] environment to be used.
\item[\code{FUN}] the function to be applied.

\begin{ExampleCode}
env <- new.env()
env$a <- 1:10
env$beta <- exp(-3:3)
env$logic <- c(TRUE,FALSE,FALSE,TRUE)
# compute the list mean for each list element
eapply(env,mean)
# median and quartiles for each list element
eapply(env, quantile, probs = 1:3/4)
eapply(env, quantile)
