Run an R function in the background, possibly after a delay. The current

version uses the Tcl event loop and was ported from the 'tcltk2' package.

## Installation

```r

source("https://install-github.me/gaborcsardi/after")

```

## Usage

```r

library(after)

```

Run a function five seconds later:

```r

after(5000, function() cat("Here I am!\n"))

```

Call a function in a package. It is good practice to create an

anonymous function for this:

```r

after(5000, function() utils::alarm())

```

Run a function every three seconds:

```r

id <- after(3000, function() cat("Still here!\n"), redo = Inf)

Sys.sleep(10)

```

```

Still here!

Still here!

Still here!

```

Cancel it:

```r

after$cancel(id)

```
