 For the R community, Computo relies on the [**renv**](https://rstudio.github.io/renv/articles/renv.html) package manager to setup a reproducible environment that handles `R` dependencies. Setting up **renv** for use within your repository requires the following steps. First,
 
-```{r}
-#| eval: false
+```r
 # Initialize your repo to work with renv
 renv::init()
 ```
 
 will set up your repository for using **renv**. Then, install the required dependencies as usual (via `install.packages()` or via the RStudio IDE) or using **renv** built-in `install()` function:
 
-```{r}
-#| eval: false
+```r
 # Install packages you need
 renv::install("ggplot2") # or equivalently install.packages("ggplot2")
 ```
 
 Non-CRAN packages (*e.g.* Github packages) can be used. To install such packages, you need to first install the **remotes** package. Then, if you want to install the development version of *e.g.* the **gt** package hosted by `rstudio` GitHub account (useful for nicely and easily formatting tables btw), you would do:
 
-```{r}
-#| eval: false
+```r
 install.packages("remotes")
 remotes::install_github("rstudio/gt")
 ```
 
 Once you are done, you need to freeze the environment and package versions that are going to be used to run the calculations within your paper. This is achieved via:
 
-```{r}
-#| eval: false
+```r
 # Register environment and package versions
 renv::snapshot()
 ```
