Officedown: Error: 'rpptx_document2' is not an exported object from 'namespace:officedown'

Created on 13 Nov 2020 · 7Comments · Source: davidgohel/officedown

Although the manual of officedown states that 'rpptx_document2 also supports cross reference based on the syntax of the bookdown package', actually there is no function called rpptx_document2 and this halts the knitting a pptx document with an error: Error: 'rpptx_document2' is not an exported object from 'namespace:officedown'. Due to this problem, it is impossible to cross-refer a figure/table number.

[x] Provide the code that is producing the error, it has to be a minimal reproducible example.

The version of Pandoc available in my environment is good enough to produce the pptx output.

rmarkdown::pandoc_version()
[1] ‘2.10.1’

[x] Make sure you did checked you had the latest version of the package on CRAN (and on github if issue exists with CRAN version).

packageVersion("officedown")
[1] ‘0.2.0.2’

[x] Make sure you searched in the open and closed issues on the github repository.

thanks, this was a mistake and that text should not be there. It's fixed now

OK, but don't you support cross-referencing function in rpptx_document, or is there such a supplemental function already?

CLRafaelR on 13 Nov 2020

no, this is not a feature as it is not a possible feature with PowerPoint - you still can use bookdown cross-ref...

davidgohel on 13 Nov 2020

Do you mean \@ref(...)?
Actually, the following example fails to cross-refer the figure number.

---
date: "`r Sys.Date()`"
author: "Your Name"
title: "Untitled"
output: 
  officedown::rpptx_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE, fig.cap = TRUE)
library(officedown)
library(ggplot2)
library(rvg)
```

## Slide with Plot

::: columns

:::: column

```{r plot1, fig.cap='pressure'}
plot(pressure)
```

::::

:::: column

\@ref(fig:plot1)

::::

:::

This is what has been implemented for PPT:

PowerPoint

The package also enhances PowerPoint productions with R Markdown by providing a
mechanism for placing results according to the slide template contained in the
PowerPoint document used as "reference_doc". It becomes easy to add several
contents in the same slide.

The package also offers the possibility to transform your graphic instructions
into editable vector graphics (with the rvg package) by simply wrapping your
call into a call to function dml.

Thank you for giving me a good example. base_format: bookdown::powerpoint_presentation2 does the trick...
