## in RStudio

## on your command line {#cli}

Using the `devtools` package:

```r
devtools::create("foo")
```

Or, with the `mason` package:

install first:

```r
devtools::install_github("metacran/mason")
devtools::install_github("metacran/mason.rpkg")
devtools::install_github("metacran/mason.github")
```

Create a package

```r
mason::mason('github')
```

See <https://github.com/metacran/mason> for details

## usethis {#usethis}

Optionally, you can use the `usethis` package <https://github.com/r-lib/usethis> 
to help in package creation/maintainance.

```r
use_mit_license("My Name")
use_package("MASS", "Suggests")
use_dev_package("callr")
use_readme_md()
use_news_md()
use_test("my-test")
use_git()
```
