How to execute .Rprofile of each document before rendering whole project?

[JackCaster]

I have a collection of blog posts, each with a specific renv lockfile. The only way I can make quarto load the correct renv specification before rendering each posts is to include an R code chunk in the .qmd file for the post with

#| file: '.Rprofile'

or

source('.Rprofile')

or

{{< include .Rprofile >}}

Is there an alternative way to make quarto load the .Rprofile automatically?

This is related to #6864, rstudio/blogdown#469 but I was not satisfied with the suggestions there, unfortunately

Quarto does not support document specific environments.
The answer remains exactly the same as in the posts you shared.

This is a duplicate of:

Ok I see. But .Rprofile can be used for other R-specific settings/options that are usually loaded by default when R is started (let's forget renv for a moment). Is .Rprofile loaded automatically by Quarto before each rendering? I can't understand if it does...

[mcanouil]

yes, if at the root of the project.
When and where R starts if there is an .Rprofile, it is loaded, but that's R behaviour unrelated to Quarto.

Is this the case? It doesn't seem to load .Rprofile if is not in the same folder as the Quarto file.

I can guarantee it is, I'm using .Rprofile in all my Quarto projects.
The .Rprofile needs to be located at the execution directory which is defined either by the document or _quarto.yml.
