I have been using R and C++ for my research in finance. For now, I can handle most econometric models with R (from OLS to MCMC, etc.), and really feel comfortable with the Hadley Wickham style data manipulation, so I think I will stick with R in the rest of my career. I would like to know if there are any online R codes shared by finance professors. I want to see how top scholars write their R codes in finance research in a finance style. I mean, I kind of feel my programming is in a math or statistic style, not in a finance style. I want to add more finance flavor to my coding style.
