I love programming in R. I know python too, but I enjoy R a bit more, because I tend to think like a statistician. And R matches that a little better. Here are a few of the portfolio (demonstration) projects I am working on:
Revisiting the Cross-Sectional Association Between Missing Teeth and Cardiovascular Disease: BRFSS 2018
Sample Descriptive Analysis Using Publicly Available Healthcare Data (BRFSS 2018 Data)
Daily information summary of economic indicators available from FRED, FRB St. Louis
Analyses with Data from Biostatistics With R by Babak Shahbaba
