How to set df_print to tibble in markdown for a single R code chunk

I would like to show, in an rmarkdown document, the printed output of a tibble as shown in the console. i.e.

  • First line: dimension summary;
  • then the column headers;
  • then classes of variables;
  • then first 10 lines of the tibble;
  • then number of rows not shown.

However, by default, tibbles and other data.frame objects are automatically converted to a tabbed, paginated table showing all contents.

I note that the option to turn off this default behaviour can be set for a whole markdown document by changing the df_print option to tibble in the YAML.

However, how do I set the df_print option to tibble for just a single R code chunk, so that I can show in an Rmarkdown document what the user will see on the console?

Thanks, Jon

There's no need to touch the global setting. You can explicitly call the print function tibble:::print.tbl_df(df)

Example:

title: "Untitled"
author: "TC"
date: "7/27/2018"
output: 
  html_document:
    df_print: "kable"
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## print tibble

```{r}
df <- tibble::as.tibble(mtcars)

tibble:::print.tbl_df(head(df))
```

## print kable (set in YAML header)

```{r}
head(df)
```
