Hi @bernahgrl, welcome to RStudio Community.
It would be much easier for people to help you if you post a reproducible example (or reprex). Please read this post to learn how to create a minimal reprex.
In the absence of a reprex, I can only provide general advice. summarise() only keeps the grouping variables and summary measures. If you want to retain all variables, consider using mutate() instead to add those measures into a new variable and then work with that.
aggregate() isn't a dplyr function. If you want to perform your analysis per company, you might want to add company as a grouping variable.
