如何在 {xaringan} 演示文稿中缩小 {stargazer} 表？

Question

I'm making my first Ninja Presentation and included a stargazer table that runs off the slide (too long). Any suggestions?

Reproducible table to be put in {xaringan}.

library(tidyverse)
library(stargazer)
df<-tibble(y=sample(1:100,500,replace=TRUE),x=sample(1:5,500,replace=TRUE),x2=sample(1:3,500,replace=TRUE),x3=sample(1:15,500,replace=TRUE),x4=sample(LETTERS[1:5],500,replace=TRUE))
stargazer(lm(df$y~df$x+df$x2+df$x3+df$x4),type="html")

along with html output for those who just want to plop that in:

<table style="text-align:center"><tr><td colspan="2" style="border-bottom: 1px solid black"></td></tr><tr><td style="text-align:left"></td><td><em>Dependent variable:</em></td></tr>

Answer 1

There are many ways to make an HTML table smaller. I suggest two things here:

1. set single.row = T in stargazer::stargazer() . This gives you coefficient estimates and corresponding standard errors on the same line and hence is more space-efficient.

2. Reduce the font size. For this you need some CSS, eg table { font-size: 12px; } table { font-size: 12px; } . You may embed this in a code chunk:

    ```{css, echo = F} table { font-size: 12px; } ```

   Note that this will change the font size for all tables in your presentation. A more general approach would be to define a class for a specific table style and than assigning that class to the slide:

    ```{css, echo = F} .regression table { font-size: 12px; } ``` --- class: regression # Hello World < code producing the table >

Using the default Xaringan template, the result looks like this:
