Initialize and Maintain of {slushy} environments

Setting up the environment

Please perform the following steps to set up your slushy environment.

1. Install {slushy} from github:

devtools::install_github("GSK-Biostatistics/slushy")

2. Create a slushy_config.yml inside your project directory and customize as needed:

new_config()  

3. Initialize your slushy environment by entering the following code in your RStudio console. By default, this will use the “default” config in your new slushy_config.yml file and today’s date for the snapshot.
   [NOTE: This will create some extra files and folders for use by slushy (.Rprofile, DESCRIPTION, renv/, renv.lock)]

library(slushy)
slushy_init()

4. [Optional] Add any extra packages needed. [NOTE: You will receive a message of caution, as these packages were not defined in the config file as agreed-upon packages.]

slushy_add("packagename")

5. [Optional] Remove a package if needed.

slushy_drop("packagename")

Updating the environment

In the future, you can easily update the environment forward or backward.

# default: use latest date
slushy_update()

# revert to a prior date
slushy_update(date = "2023-01-01")
