playdata

The playdata package holds all of the internal datasets for the playbase package.

Adding Rda datasets

If you have a dataset to add, you should do the following:

• read the dataset into R memory via the console
• make sure the dataset variable is named as it will be called in playdata
• run usethis::use_data(DATASET_NAME)
• add a documentation entry in R/playdata-data.R
• run devtools::document() to update the documentation

Now you can call the dataset via playdata::DATASET_NAME

Updating an Rda dataset

If you have a dataset to update, you should do the following:

• read the dataset into R memory via the console
• make sure the dataset variable is named as it will be called in playdata
• run usethis::use_data(DATASET_NAME, overwrite = TRUE)
• update documentation entry in R/playdata-data.R, if necessary
• run devtools::document() to update the documentation

Adding non-Rda datasets

If you have a file to add that is not in Rda format, then do the following:

• add it to the inst/extdata folder

Then you can get the path to the file via playdata::get_file(FILENAME)

Accessing playdata datasets dynamically

If you want to access playdata dataset dynamically, where for example the dataset from playdata to be accessed is only known via a variable name, then use the function playdata::get_data(...).

For example, if you want to access the dataset BLUERED, you can simply call playdata::BLUERED. But if BLUERED was a variable - e.g., mycolor <- 'BLUERED' - then you can access the dataset via playdata::get_data(mycolor).
