How can i perform a shapirowick test on a long tibble table, where there are multiple factors for different days

basically i have a table with different environment types that cells are grown in for 7 days all in one table and I want to know the easier way to compute a shapiro wick without having to import each environment as a separate one as I want to eventually compute a two way anova

You could use the group_by() and summarise() functions from dplyr.
