# Getting started {.unnumbered}

To build an R package you will need [R](https://cran.r-project.org/bin/windows/base/) installed and an IDE: preferably [R Studio](https://posit.co/download/rstudio-desktop/) or [Positron](https://github.com/posit-dev/positron/releases).

There are some packages that you will need [devtools](https://devtools.r-lib.org) and [usethis](https://usethis.r-lib.org) they are key to follow the different steps on this package building tutorial.

```{r, eval=FALSE}
install.packages("pak")
library(pak)
pkg_install("usethis")
pkg_install("devtools")
```


To work with the omopverse, you will also need to install the [omopgenerics](https://darwin-eu-dev.github.io/omopgenerics/) package. Alongside with other packages that may be useful:

- [PatientProfiles](https://darwin-eu-dev.github.io/PatientProfiles/) for data manipulation.
- [CodelistDiagnostics](https://darwin-eu.github.io/CodelistDiagnostics/) to query the vocabularies.
- [visOmopResults](https://darwin-eu.github.io/visOmopResults/) for data visualisation.

You can see the list of the omopverse packages in our [website](https://oxford-pharmacoepi.github.io/Oxinfer/packages.html).
