I love all of its tools that i can do using it especially when we are talking about data analysis, you definitely cannot miss this program! what is lacking in terms of user experience? nothing as longs to explore everything from every end until there was never anything wrong with our needs or expectations so far but if at anywhere else then just trust me guys!! Data analytics & statistical reportsData miningR programmingThe ease-of -useEasy learningCurves I like that it is very easy to use, also that it has a lot of options to customize the way you want it to work. Sometimes there are some bugs but nothing too serious. I would recommend this program to anyone who wants a good program to use with excel. I am using it in order to make my business more organized. This allows me to keep track of all my expenses and make sure everything is correct and organized.
