Problems with knitr and rmarkdown

[DES Alfonso Cano Robles]

Hello to all, once again thanking you all for all the hard work that you
have been putting into RKWard.

I've been using RKWard

   - R. Version 0.7.5z+0.7.6+devel1. https://rkward.kde.org
   - With R cran base v4.3.1
   - System:
     Kernel: 5.15.0-86-generic x86_64 bits: 64 compiler: gcc v: 11.4.0
   Desktop: Cinnamon 5.8.4
       tk: GTK 3.24.33 wm: muffin dm: LightDM Distro: Linux Mint 21.2
   Victoria base: Ubuntu 22.04 jammy

Since I've updated to linux mint 21, I have tried to execute the next code
from the export markdown menu:

local({
> ## Preparar
> require(knitr)
> require(rmarkdown)
> rk.check.for.pandoc(
>   stop_if_missing=TRUE,
>   output_format="latex"
> )

## Computar
> render(
>   input="/home/cano/Escritorio/ENOE/Importclean/proyecto.Rmd",
>   output_format="pdf_document",
>   output_file="/home/cano/Escritorio/ENOE/Importclean/proyecto.pdf",
>   quiet=TRUE
> )
> ## Imprimir el resultado
> rk.header ("Exportar archivo RMarkdown", parameters=list("Archivo
> RMarkdown"="/home/user//proyecto.Rmd",
> "Formato de destino"="PDF",
> "Guardar como"="/home/user/proyecto.pdf"))
> })


But when starting to evaluate R code from lines 51-54, I have got:

Loading required package: knitr
Loading required package: rmarkdown

Quitting from lines 51-54 [unnamed-chunk-1] (proyecto.Rmd)
Error in `.rk.do.call()`:
! no se pudo encontrar la función ".rk.do.call"
Backtrace:

 17. base::mapply(...)
 18. knitr (local) `<fn>`(...)
 21. knitr:::plot2dev(...)
 22. grDevices::dev.off()

Quitting from lines 51-54 [unnamed-chunk-1] (proyecto.Rmd)
Error in `.rk.do.call()`:
! no se pudo encontrar la función ".rk.do.call"
Backtrace:

  8. knitr:::call_block(x)
  9. knitr:::block_exec(params)
 10. knitr:::eng_r(options)
 11. grDevices::dev.off(dv)


States  that the function ".rk.do.call" has not been found.
I didn't have this problem on the previous version of mint.  Is it possible
to fix this?
Thanks to all.
Best regards
Alfonso.
