R is making more sense and getting easier, or I should probably say more familiar. I have learned to code the simple straightforward tasks without help or having to copy and paste. SAS was much harder for me. Maybe it’s just that I learned so much in the SAS section that it was easier to transition to R. Either way I feel much more confident in R.
This week we were focused on Regression Analysis. I am amazed at how easy running the model is. Both SAS and R are capable of running the actual model with just a few lines of code. However you may have hundreds of lines of code to load, scrub, transform and stage the data the right way. That is definitely the hard part. I can think of about a thousand different analogies that fit this process. When everything is clean and correct, the regression model is very simple.
The lesson here is…..DATA IS RARELY CLEAN!
