Regression Tables in R Markdown / rmarkdown (html/pdf)

Question

For the purpose of publishing I often need both a PDF and a HTML version of my work including regression tables and I want to use R Markdown. For PDF the stargazer

Answer 1

Here is a proposition: make a function that checks the output format and then uses either stargazer or texreg depending on this. We use opts_knit$get("rmarkdown.pandoc.to") to check the output format.

output: html_document

```{r setup, include=FALSE}
library(knitr)
opts_chunk$set(echo = TRUE)
rmd_format <- opts_knit$get("rmarkdown.pandoc.to")
## returns "html" or "latex"

```

```{r}

report_regression <- function(model, format, ...){
  if(format == "html"){
    require(texreg)
    htmlreg(model, custom.note="%stars. htmlreg", ...)
  } else if(format == "latex"){
    require(stargazer)
    stargazer(model, notes="stargazer html", ...)
  } else {
   print("This only works with latex and html output") 
  }
}
```

```{r table, results = "asis"}
library(car)
lm1 <- lm(prestige ~ income + education, data=Duncan)

report_regression(lm1, format = rmd_format)
```
