In R Markdown documents, square brackets are often used to denote figure or table captions, such as "[Figure 1: My Caption]". If you want to suppress these square bracket figure notes in your R Markdown document, you can do so by using the `fig_caption` option and customizing the YAML metadata header.
Here's how to achieve this:
1. **Customize the YAML Metadata:**
In the YAML metadata header at the top of your R Markdown document, you can specify the `fig_caption` option to control how figure captions are formatted. To suppress square brackets, set it to an empty string or to a custom format.
For example, in your R Markdown document:
```yaml
---
title: "My R Markdown Document"
output:
html_document:
fig_caption: ""
---
```
This will suppress the square bracket figure notes in the HTML output.
2. **Specify Custom Figure Captions:**
If you want to provide your own custom figure captions without square brackets, you can do so explicitly when creating figures. For example:
```{r my_plot, fig.cap="My Custom Caption"}
# R code to create the plot
```
In this case, the figure caption will be "My Custom Caption" without any square brackets.
Customizing the `fig_caption` option and specifying custom captions allows you to control how figure captions are displayed in your R Markdown document, including suppressing square brackets if needed.
