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 enclosing environments are searched.
This is a primitive function.
eapply(env, FUN, ..., all.names = FALSE, USE.NAMES = TRUE)
- environment to be used.
- the function to be applied, found via
match.fun. In the case of functions like
%*%, etc., the function name must be backquoted or quoted.
- optional arguments to
- a logical indicating whether to apply the function to all values.
- logical indicating whether the resulting list should have
A named (unless
USE.NAMES = FALSE) list. Note that the order of the components is arbitrary for hashed environments.
require(stats) env <- new.env(hash = FALSE) # so the order is fixed env$a <- 1:10 env$beta <- exp(-3:3) env$logic <- c(TRUE, FALSE, FALSE, TRUE) # what have we there? utils::ls.str(env) # compute the mean for each list element eapply(env, mean) unlist(eapply(env, mean, USE.NAMES = FALSE)) # median and quartiles for each element (making use of "..." passing): eapply(env, quantile, probs = 1:3/4) eapply(env, quantile)
