I just preprinted my first 1st-author paper. Exciting! You can find it here: How Many Psychologists Use Questionable Research Practices?
I used this paper as a project to learn how to create a fully reproducible paper. By that, I mean a person could take my data files and my “paper” file and fully reproduce the paper (including analyses, figures, tables, etc) and the final document all in one step. The special part of this process is the “paper” file.
