# b. dt.csv (1000 x 9): date and time variables (see book chapter 10_times.Rmd)
# - Consider combining with dataset `outliers` (1000 x 3), BUT: different genders and height values and regularities
# - Collect ds4psy survey data
# - Find some book/text to analyze (Chapter 9: Text data).
# - Add text data (Chapter 9: Text; e.g., dinos, fruit, veggies, attention check response on "i read instructions", some eBook for sentinent analysis, ...)
# - Add more info to codebooks (see data_190807.R in archive)

## Check data: ------
## Check for "marked UTF-8 strings":
# tools:::.check_package_datasets(".")
## ToDo: ----------
# - Add date/time data (Chapter 10: Time, e.g., DOB, time of test, task start/end, etc.)
# - Combine 2 datasets (currently online):
# a. numeracy.csv (1000 x 12, see book chapter 55_datasets.Rmd),
# b. dt.csv (1000 x 9): date and time variables (see book chapter 10_times.Rmd)
# - Consider combining with dataset `outliers` (1000 x 3), BUT: different genders and height values and regularities
# - Collect ds4psy survey data
# - Find some book/text to analyze (Chapter 9: Text data).
# - Add text data (Chapter 9: Text; e.g., dinos, fruit, veggies, attention check response on "i read instructions", some eBook for sentinent analysis, ...)
# - Add more info to codebooks (see data_190807.R in archive)
