# mlapply: Apply a Function of Multiple Arguments In ENmisc: Neuwirth miscellaneous

## Description

`mlapply` returns a list of the same length as each of the lists in `lol`. Each element of the resulting list is the result of applying `FUN` to all the first elements of the lists in lol, all the second elements of the lists in lol ...
It is the multivariate version of `lapply`

## Usage

 `1` ```mlapply(lol,FUN,...) ```

## Arguments

 `lol` a list of lists, the elements of each list will be used as arguments to calls to `FUN` `FUN` the function to be applied. In the case of functions like `+`, `%*%`, etc., the function name must be backquoted or quoted. `...` Any additional arguments passed to each call to `FUN`

## Value

`FUN` is a function with the number of arguments being equal to the number of lists contained in `lol`.
`mlapply` makes a function call to `FUN` for all the first elements of all the lists in `lol`, then a function call to all the second elements of all the lists in `lol`, and retunrs all the results as a list.
If the first list in `lol` has named elements, the names will also be used for the elements of the resulting list.

`link{lapply}`

## Examples

 ```1 2 3 4``` ```mlapply(list(list(1,2,3),list(4,5,6)),function(x,y)x^2+y^2) mlapply(list(list(a=1,b=2,c=3),list(4,5,6)),function(x,y)x^2+y^2) mlapply(list(list(a=1,b=2,c=3),list(4,5,6)),function(x,y,e)x^e+y^e,3) mlapply(list(list(1,2,3),list(4,5,6)),function(x,y,const=0)x^2+y^2+const) ```
