This is a slightly modified version of the excellent stargazer package by Marek Hlavac.
In contrast to the main package, this fork outputs tables which use the booktabs commands \toprule \midrule and \bottomrule for horizontal rules.
To install:
install.packages("devtools")
library(devtools)
install_github("markwestcott34/stargazer-booktabs")Make sure you include \usepackage{booktabs} in your LaTeX preamble.
See the vignette for example output.
