## Installation

Install the release version from CRAN:

```r

install.packages("quantities")

```

The installation from GitHub requires the [remotes](https://cran.r-project.org/package=remotes) package.

```r

# install.packages("remotes")

remotes::install_github(paste("r-quantities", c("units", "errors", "quantities"), sep="/"))

```
