Is there a way to add line breaks ONLY when exporting to PDF in R Markdown?

I think the question is quite self-explanatory but for avoidance of doubt I'll explain with more detail below:

I have an R Markdown document that works well if converted to HTML or uploaded to GitHub. When converting to PDF (using Latex), the results are not so pretty. I find that the biggest problem in a Latex PDF document are line breaks. I can fix the line breaks issue on the PDF document by adding "\ " characters, but that throws my HTML document out of whack too.

Is there a way to manually add line breaks (or "space before/after paragraphs") for the PDF output only?

Thank you!

You can redefine the relevant spacings in the YAML header. \parskip controls the paragraph spacing. Code blocks are shaded using a snugshade environment from the framed package. We can also redefine the shaded environment for code blocks to have some vertical space at the start. Here's a reproducible example. Note: I also added the keep_tex parameter so you can see exactly what the generated tex file looks like, in case this is useful:

title: "test"
author: "A.N. Other"
header-includes:
   - \setlength{\parskip}{\baselineskip}
   - \renewenvironment{Shaded}{\vspace{\parskip}\begin{snugshade}}{\end{snugshade}}
output: 
  pdf_document:
    keep_tex: true
---

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

## R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r cars}
summary(cars)
```

## Including Plots

You can also embed plots, for example:

```{r pressure, echo=FALSE}
plot(pressure)
```

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.

Once you output to HTML, you can just print the HTML webpage as PDF. that might be an easy way keep the original format
