This post briefly introduces my personal preference writing R code with Rstudio. This is not to say this is the best way, but I think it fits me at least.
This post briefly introduces how to use Git to share your work and connect your Github with Rstudio.
This post briefly introduces how to make R packages. For more details, you can check this Write R Extensions; but it is hard for beginnners to read through these details, so I recommend the Hadley’s R Packages book. This is a very reader-friendly book that introduces the infrastructure of R packages and the basic processes that we make R packages.
This post introduces R style guide from google community. It is very useful for beginners to learn how to code in an appropriate way that can share with other scholars. The basic goal of this post is to introduce the commonly used coding styles.
This post shows the R learning materials I have compiled regarding code style guide, useful packages, and some projects that I have worked on.

This study examines local factors that influenced whether and when desegregation orders were dismissed between 1970 and 2013.
This talk introduces a paper that uses the propensity score matching (PSM) method to analyze the cohabitation effect in urban China: the relationship between premarital cohabitation and marital disruption. Using data on urban individuals married during 1978-1999 and 2000-2010 from Chinese Family Panel Studies in 2010, this article matches married ones with cohabitation histories prior to first marriage—whether cohabited with the spouse or not, and applies Cox Proportional Hazards Models to explore how premarital cohabitation affects an individual’s subsequent divorce hazards of first marriage.
This talk introduces a paper entitled “Social Network, Relative Deprivation, and Protest Propensity in Urban China: A Structural-Cognitive Approach.”
This talk, with Andrew Davis, introduces a paper entitled “Terrorism and Civil Society: Organizational Opportunity and Repression in Cross-National Perspective, 1970-2006.”
This talk introduces a paper on “Theming for Terror: Organizational Adornment in Terrorist Propaganda.”
This talk introduces a paper on “With All Deliberate Speed: The Reversal of Court-Ordered School Desegregation in the United States, 1970-2013.”
