+## Re-running analysis
+
+Using RStudio open [main.R](https://github.com/rubysaltbush/floral-longevity/blob/main/main.R) 
+and run scripts in order given in this main script.
+
+Necessary packages can be installed by running [install_dependencies.R](https://github.com/rubysaltbush/floral-longevity/blob/main/scripts/install_dependencies.R).
+Check package versions mentioned in this script are consistent with your installed versions. 
+Originally run in R version 4.3.0
+
+The code caches several steps of the data cleaning and results.
