Betsy Levy Paluck Lab R Package

This package is a collection of functions I wrote during my time as lab manager to facilitate transparent social science. This is a place where lab members can share code and functions they have written together, and learn how to contribute to open-source software.

There are loosely two groups of functions that lab members will find most useful. The first is the workhorse tidy_lm function that runs many regressions models with support for clustered standard errors and presents them in a tidy format.

tidy_lm can supports multiple "styles" of models. These are:

• default uses all terms at once on all the DVs.

y_1 ~ x_1 + x_2 + x_3
y_2 ~ x_1 + x_2 + x_3
y_3 ~ x_1 + x_2 + x_3

• incremental starts off with one term and adds one more term each model for each dv.

y_1 ~ x_1
y_1 ~ x_1 + x_2 
y_1 ~ x_1 + x_2 + x_3
y_2 ~ x_1
y_2 ~ x_1 + x_2 
y_2 ~ x_1 + x_2 + x_3

• chord begins by running a bivariate regression the first term. Then runs a trivariate regression, holding the dv, first is term constant looping through the remaining terms. Lastly, all terms are ran together.

y_1 ~ x_1
y_1 ~ x_1 + x_2 
y_1 ~ x_1 + x_3
y_1 ~ x_1 + x_2 + x_3
y_2 ~ x_1
y_2 ~ x_1 + x_2 
y_2 ~ x_1 + x_3
y_2 ~ x_1 + x_2 + x_3

• bivariate uses all terms individually on each dv.

y_1 ~ x_1
y_1 ~ x_2 
y_1 ~ x_3
y_2 ~ x_1
y_2 ~ x_2 
y_2 ~ x_3

The second are custom hacks for creating publication quality tables. This is useful for editing tables created by stargazer, knitr::kable or kableExtra. These are numerous and mostly self-explanatory.

• table_label Adds dynamic labels to that can be references elsewhere in your .tex file or RMarkdown document via \label{tab:your_label_here}

• add_endnote Improvement to footnotes from stargazer function with an additional size_in_inches argument to allow for custom sizes

• stargazer_pvalues the p-values in stargazer are clunky. This reformats the p-values to be 'brackets', 'parentheses' or 'none' to replace the stargazer default.

• stargazer_rowname add custom text to the first column in stargazer

• print_table A cleaner way to print LaTeX tables than simply using the cat(). Equivalent to cat(paste(latex_table, collapse = "\n"))

• kable_resize An option for when kable_styling(full_width = F, latex_options = "scale_down") isn't enough.

• table_numbers Adds custom numbers to a table. Useful for adding secondary counts to tables (e.g., Table 2a, Table 2b). Can also be used to switch primary counts to alternative styles like alph or roman. Requires header needs \newcounter{foo} to be added in document YAML to work under header-includes:

• two_digits Rounds numbers to the second digit, and returns them as a character in two digits. Useful for number consistency during visualization.

• add_top_row

• add_bottom_row

• add_parentheses

• add_brackets
