Description
Bug description
Setting the knitr option for global device to true results in an unexpected behavior where the initial plot is displayed after each code chunk.
Steps to reproduce
---
title: "test"
format: html
embed-resources: true
---
```{r}
knitr::opts_knit$set(global.device = TRUE)
```
First a plot with default parameters:
```{r}
plot(1:10)
```
Now let's change the color:
```{r}
par(col="red")
```
And we plot again:
```{r}
plot(1:10)
```
or
---
title: "test"
format: html
knitr:
opts_knit:
global.device: true
embed-resources: true
---
First a plot with default parameters:
```{r}
plot(1:10)
```
Now let's change the color:
```{r}
par(col="red")
```
And we plot again:
```{r}
plot(1:10)
```
Expected behavior
Resulting plots from code chunk render once after their respective chunk.
Actual behavior
Initial plot gets rendered after each code chunk.
