Why is R markdown not able to format my patchwork figure?

Question

I have a question regarding markdown and patchwork. Let's say I combined figures FigureLength and FigureWidth to make CombinedFigure through patchwork (two figures on top of each other):

library(datasets)
library(patchwork)
data(iris)

FigureLength <- iris %>% 
  ggplot(aes(x = Species, y = Sepal.Length)) +
  geom_boxplot()

FigureWidth <- iris %>% 
  ggplot(aes(x = Species, y = Sepal.Width)) +
  geom_boxplot()

CombinedFigure <- FigureLength / FigureWidth

Both figures nicely on top of each other in R

save(CombinedFigure, file = here::here ("CombinedFigure"))

In Markdown when I put the following only Sepal Length appears in my word document and not both figures on top of each other.

```{r CombinedFigure,   dpi = 300, echo = FALSE}
CombinedFigure
```

What appears in markdown - only one figure

Thanks for your help.

Answer 1

When I run the following code:

---
title: "Untitled"
author: "Author"
date: "4/4/2022"
output: word_document
---

```{r}
library(datasets)
library(tidyverse)
library(patchwork)
data(iris)

FigureLength <- iris %>% 
  ggplot(aes(x = Species, y = Sepal.Length)) +
  geom_boxplot()

FigureWidth <- iris %>% 
  ggplot(aes(x = Species, y = Sepal.Width)) +
  geom_boxplot()

CombinedFigure <- FigureLength / FigureWidth
```

```{r CombinedFigure,   dpi = 300, echo = FALSE}
CombinedFigure
```

I to get both figures nicely on top of each other in WORD like this:
