knit broken, no rmarkdown, need newer pandoc to match R 4.0.0 ?

[jp3]

I am new to rstudio and rmarkdown. I am running R 4.0.0 from AUR on manjaro stable. In the last few weeks I installed tidyverse and a few other packages; rmarkdown seems to come with rstudio.

I updated all packages. Then when I try to knit I get these:

"Error: pandoc version 1.12.3 or higher is required and was not found (see the help page ?rmarkdown::pandoc_available)."

and then

install.packages("pandoc")
Installing package into ‘/home/joe/R/x86_64-pc-linux-gnu-library/4.0’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘pandoc’ is not available (for R version 4.0.0)

It seems I am caught in a loop.
Is a new version of pandoc forthcoming?
In the meantime, how can I get around this? It is not clear to me how to revert R to an earlier version, and if so, which one would be compatible with the current other packages...

Any ideas on how to repair the installation so I can use rstudio projects and rmarkdown ?

Thanks.

pandoc is not an R package but a tool that you can install separately.
As far as I know it is included in RStudio.
So if you installed a recent version of RStudio you will also have a recent version of pandoc.
So my conclusion: you have not a recent version of RStudio. (?)
Is it possible for you to install the latest (standard) version?

Seems fixed after I updated R to 4.0.1-1 with other system installs and updates, and it will knit now.

Thank you for the advice.
