Hi everyone, this is going to be a simple manual for learning and using R commands for your data analysis. Learning R was not easy for me. whenever I wanted to run a simple command, I had to go through a very detailed explanation that I would often lose track of. Therefore, I wanted to create a simple instruction for anyone who is just learning to use R and to not suffer as I did. This manual is useful for anyone who has just started using R and needs to understand the function and instruction for the commands. Please make sure you have the R studio installed and check out this pdf to get started!
