Hi all! I am a masters student in Germany currently taking a machine learning course in R and writing a master thesis with the help of R (for collecting data). I have taken one data analysis university course before which was based in R. Though this course was intense, I have not had much practice with R since last semester. Thus, I still consider myself a beginner. I appreciate your help/comments with my questions and I hope to learn enough so that I can contribute back to the stack overflow community.
