Code chunks and inline R code

• You should define the object for the number in the code chunck, so that you can use that number in the narratives of the project document.

R Markdown Code

library(tidyverse)
oj <- read_csv('https://bcecon.github.io/dominick_oj.csv')
nvars <- format(round(ncol(oj), 0), 
                nsmall=0, 
                big.mark=",") 
nobs <- format(round(nrow(oj), 0), 
                nsmall=0, 
                big.mark=",")Copy Code

The number of variables is `r nvars`; the number of observations is `r nobs`.

Output

The number of variables is 4; the number of observations is 28,947.

Roses are red, violets are blue.

Font color

• The Markdown syntax has no built-in method for changing text colors. We can use HTML syntax to change the formatting of words:

R Markdown Code

Roses are <span style="color: red;">red</span>, violets are <span style="color: blue;">blue</span>.Copy Code

Output

Roses are red, violets are blue.

Spacing

• To add a space between paragraphs or lines, you can use <br>.

YAML

• Here is an example of the YAML metadata for an HTML document from R Markdown:

title: "TITLE_OF_YOUR_PROJECT"
subtitle: "SUBTITLE_OF_YOUR_PROJECT<br><br>" 
author: 
  - "AUTHOR_1"
  - "AUTHOR_2"
  - <br>
date: "2022-04-14<br><br>"
output: 
  html_document:
    df_print: paged
    toc: true
    toc_depth: 2
    toc_float: true
    number_sections: true
    theme: united
