Render RStudio version number with quarto

[KipBalkcom-USDA]

Description

I want to render my RStudio version number in a quarto document. The example below shows different ways I have tried to do this. I can run rstudioapi::getVersion() or RStudio.Version() in the R console to get my RStudio version number, but I wanted to do this during the rendering process. Any ideas?

R version 4.5.0 (2025-04-11)
Quarto version 1.7.32
Running under: macOS Sequoia 15.6.1

---
format: html
---

```{r}
rstudio <- rstudioapi::getVersion()

rstudio2 <- RStudio.Version()
```

My Rstudio version is `{r} rstudio`
The above line gives me an error that "RStudio not running."

My Rstudio version is `{r} rstudio2`
The above line gives me an error that states "error in `Rstudio.Version()`"

My RStudio version is `{r} rstudioapi::getVersion()`
The above line gives me an error that states "RStudio not running"

Yeah, that's not a thing that I think will work; the "RStudio not running" message is accurate: quarto render doesn't happen inside an RStudio R session, and so it is correct to say that RStudio isn't running.

Can you say a bit more about what you're trying to do?

I would like to programmatically enter the RStudio version number in my quarto document. Similary, I have listed R packages used in my analyses with their version numbers (e.g., {r} packageVersion("ggplot2")) along with the version of R used {r} R.version.string. I simply wanted to include the RStudio version number also.

This is the thing - "the RStudio" version is not information that's available to Quarto in the same way that it is available to RMarkdown. RMarkdown runs in the active RStudio R session, but Quarto is a standalone program, and when Quarto uses knitr to render, it doesn't know about RStudio at all. So the information really isn't there for rstudioapi to find it, because the RStudio API really isn't available to Quarto.

ok. So it sounds like there is no way to enter the RStudio version info in a Quarto document unless I enter the information manually. Correct? If so, I will enter it manually. Thanks.

The only way I can think of would be to use the R wrapper to Quarto CLI, and pass metadata/parameters (as preferred).

ok, I will have to investigate that further. I am not familiar with those concepts. I currently render inside RStudio and not with the CLI.
