She encourages R to email her with any questions that arise between lessons and she responds to them very quickly. Our daughter comes out of a two hour lesson wishing she could stay longer. When Frances suggested R have a few longer lessons in order to work on some skills that couldn't be developed in just a two hour lesson, R was enthusiastic, even though it meant giving up time on the weekend to do it. This is the type of enthusiasm every teacher should be able to bring out in her student!
I could tell how much he cares about a students learning experience, and creating a comfortable environment that makes it valuable for the learner - I never felt talked down to during our lesson nor did he ever have an impatient tone... All in all, I walked away from our lesson with more understanding of the R programming language, how to work in the R Studio IDE, and more knowledgeable about some of the key points in Machine Learning with R.
Christian helped me with R Studio using R Code. He was able to walk me through some fixes of issues I was having with R in general. He was patient and understands R well. Thanks!
