I like that it's easy for people new into data analysis/statistics since you can easily create graphs using RStudio which makes things easier than when working with Excel or other software packages where creating charts manually would be difficult (or even impossible).
Also i love how simple yet powerful this program really was once we got used too its functions! The only downside about protège so far has been having some issues while trying out different programs such as Matlab but those problems were solved pretty quickly after contacting support team via emailing them at contact@protegeteam.com.
