Record and play back your R

`rec` captures code evaluation and output, trying to preserve the R objects, 

console output and conditions (messages, warnings and errors) emitted during 

evaluation.

## Quick Start

`rec` operates in one of two ways, either recording an expression's evaluation, 

or recording the top level interactive console. In both, cases, you can use 

the singular interface, `rec()`. Once you've recorded evaluation, you

can also play it back!

### Record your console

Recording your console is started and stopped by running `rec()`. While

recording, you'll see a ":red_circle:" in front of your command prompt,

indicating that you're in a recording session.

```r

rec()

print(1:3)

# [1] 1 2 3

rec()  # stop recording

play()

# print(1:3)

# [1] 1 2 3

```

### Record expression evaluation

Alternatively, you may want to capture evaluation in the background. This can be

A helpful alternative to `capture.output`, for situations where you want to

capture messages, but want to restructure the formatting or operate 

```r

recording <- rec(print(1:3))

# [1] 1 2 3

play(recording)

# print(1:3)

# [1] 1 2 3

```
