rmarkdown text and plot

[app9j]

Hi,

In the code below I am looking to show text on a slide then below that show a plot. I am trying to do that in a one-column format on the "Slide with Plot" and in a two-column format on the "Two Column Slide". Can you advise how that is possible?

Below the text appears but the plots do not appear using plot() or print(plot()).

Thank you

2## R Markdown
This is an R Markdown presentation. 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.

## Slide with Bullets

- Bullet 1
- Bullet 2
- Bullet 3



## Slide with R Output

```{r cars, echo = TRUE}
summary(cars)

```



## Slide with Plot

some text  

```{r pressure, echo= FALSE, comment = FALSE, message= FALSE, warning = FALSE, results='asis'}

cat("\n\n more text")
plot(pressure)
cat("\n\n")

```

## Two Column Slide

:::::::::::::: {.columns}
::: {.column}

1st column test
```{r pressure2, echo= FALSE, comment = FALSE, message= FALSE, warning = FALSE, results='asis'}

cat("\n\n More 1st column text \n\n")
plot(pressure)  
cat("\n\n")

```
:::
::: {.column}

2nd column text

```{r pressure80}

print(plot(pressure))
```

You can't really use results = 'asis' with plot inside the chunk. The plot won't be process as it should by knitr.
Results asis is for including a cat() output asis in the markdown document. Plot won't return something you can include like this.

I think you need a recent version of Pandoc for this to work. You may need to use RStudio IDE daily version or install a recent pandoc yourself.

This is because you need to have the Comparison layout available (Pandoc - Pandoc User’s Guide)

Then you should be able to use text and plot in the same column

## Two Column Slide

:::::::::::::: {.columns}
::: {.column}

1st column test

```{r pressure2, echo= FALSE, comment = FALSE, message= FALSE, warning = FALSE}
plot(pressure)  
```
:::
::: {.column}

2nd column text

```{r pressure80}
print(plot(pressure))
```

Thank you. I have pandoc version 2.7.2 and rmarkdown 2.1 and running your code above does not show the plots. Do you know versions are necessary for the comparison layout?

@app9j

have pandoc version 2.7.2

At least Pandoc 2.15 I believe

[app9j]

I have 2.7.2 so I think it should work but no luck. I am using reference_doc: template.pptx and I added a layout slide in that pptx file called "Comparison" with the comparison layout but I still do not see the plot. Also, to tesst, I removed the reference_doc: template.pptx and no plots appeared.

The template.pptx file now has 5 layouts. The 4 listed here: https://support.rstudio.com/hc/en-us/articles/360004672913-Rendering-PowerPoint-Presentations-with-the-RStudio-IDE plus the comparison layout.

[app9j]

Any thought on why it doesn't work with 2.7.2?

[cderv]

Because it requires Pandoc 2.15 at least, which is newer than 2.7.2. You have a version which is too old as I said above.
