Automated, Reproducible Generation of Results Tables: Bridging the Rift Between Epidemiologists and Their Data
Tables are the key format in which epidemiologists present their results. Many results tables in applied studies merely show point estimates and confidence intervals, or even p-values, from regression models: a “growing rift between epidemiologists and their data” (Rothman 2017). “Actual,” descriptive data, such as counts stratified by exposure and a main confounder or effect modifier, are often lacking.
rifttable creates presentation-ready results tables for epidemiologists in an automated, reproducible fashion. The user provides the final analytical dataset and specifies the design of the table, with rows and/or columns defined by exposure(s), effect modifier(s), and estimands as desired, allowing to show descriptors and inferential estimates in one table – bridging the rift between epidemiologists and their data, one table at a time.
You can install the development version of rifttable directly from GitHub:
remotes::install_github("stopsack/rifttable")The installation procedure requires the {remotes} package, obtainable
via install.packages("remotes").
