Recall {base} | R Documentation

## Recursive Calling

### Description

`Recall` is used as a placeholder for the name of the function in which it is called. It allows the definition of recursive functions which still work after being renamed, see example below.

### Usage

    Recall(...)

### Arguments

`...` | all the arguments to be passed.

### See Also

`do.call` and `call`.

### Examples

    ## A trivial (but inefficient!) example:
    fib <- function(n) if(n<=2) {if(n>=0) 1 else 0} else Recall(n-1) + Recall(n-2)
    fibonacci <- fib; rm(fib)
    ## renaming wouldn't work without Recall
    fibonacci(10) # 55
