mapply()Recursively apply a function to a list or lists.
rMapply(FUN, ..., MoreArgs = NULL, SIMPLIFY = TRUE, USE.NAMES = TRUE)The output of FUN in a list or nested list, or simplified to a
vector or array (or list of arrays).
Function to apply.
Object(s) to which FUN can be applied, or lists of such objects
to iterate over (defined narrowly, as of class "list").
A list of additional arguments to FUN.
Logical, whether to simplify the results to a vector or array.
Logical, whether to use the names of the first list object
in ... for the output.
rMapply() recursively applies FUN to the elements of the lists
in ... via mapply(). If only a single list is supplied, the function
acts like a recursive version of sapply(). The particular condition that
determines if the function should stop recursing is if either the first or
second objects in ... are not of class "list". Thus, unlike mapply(),
it will not iterate over non-list elements in these objects, but instead
returns the output of FUN(...).
This is primarily a convenience function used internally to enable
recursive application of functions to lists or nested lists. Its particular
stop condition for recursing is also designed to either a) act as a
wrapper for FUN if the first object in ... is not a list, or b) apply
a weighted averaging operation if the first object is a list and the second
object is a numeric vector of weights.
