You can install the latest released version from
[CRAN](http://cran.r-project.org/package=mkin) from within R:
-
```r
install.packages("mkin")
```
-If looking for the latest features, you can install directly from
-[github](http://github.com/jranke/mkin), e.g. using the `devtools` package.
-Using `quick = TRUE` skips docs, multiple-architecture builds, demos, and
