Good to have additional dependency specifications

[angerhang]

It would be good to know the key dependencies this package requires, for example, tested R and R studio version. It will make it easier for others to debug/contribute in the future.

Thank you @angerhang for your comment. I have added the followings into the revised version of the README (Usage section, 3rd bullet point, bold text below):

"On your machine via R software (version: ≥ 3.4.0), the RStudio environment (recommended versions: Prairie Trillium [2022.02] and newer), and the activAnalyzer package installable from CRAN (stable version) or from GitHub (development version)."

The minimum R version to be used is also indicated in the DESCRIPTION file.

Please let me know if it is not enough.
