I am trying to download rmarkdown but i get these errors:

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
namespace 'xfun' 0.13 is being loaded, but >= 0.19 is required
ERROR: lazy loading failed for package 'tinytex'

• removing 'C:/Users/Owner/Documents/R/win-library/3.5/tinytex'
  In R CMD INSTALL
  ERROR: dependencies 'knitr', 'tinytex' are not available for package 'rmarkdown'
• removing 'C:/Users/Owner/Documents/R/win-library/3.5/rmarkdown'

namespace 'xfun' 0.13 is being loaded, but >= 0.19 is required

The error message is asking you to update the xfun package

install.packages("xfun")

thank you, I tried to update but got this message

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

https://cran.rstudio.com/bin/windows/Rtools/
Installing package into ‘C:/Users/Owner/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)

  There is a binary version available but the
  source version is later:
     binary source needs_compilation
xfun   0.13   0.20              TRUE

The problem is I just downloaded rtools newest version so I am confused

thank you so much for the help

The problem is I just downloaded rtools newest version

Rtools40 is to be used with R >= 4.0.0, since you are using an old R version, you have to download a suitable version from here R for Windows Build Tools Archive
