How to get the Source Code of a function in R

We can get the source code of an R function by running the getAnywhere() command. For example, if we want to get the source code of the rle built-in function we can run:

A single object matching ‘rle’ was found
It was found in the following places
with value

function (x) 
    if (!is.vector(x) && !is.list(x)) 
        stop("'x' must be a vector of an atomic type")
    n <- length(x)
    if (n == 0L) 
        return(structure(list(lengths = integer(), values = x), 
            class = "rle"))
    y <- x[-1L] != x[-n]
    i <- c(which(y |, n)
    structure(list(lengths = diff(c(0L, i)), values = x[i]), 
        class = "rle")

For more information, you can have a look at the Stackoverflow discussion. Finally, we have written a post on how to get the source code of a function in Python.
