[Pradip]

Hello, 
My attempt to knit an .Rmd file to PDF from RStudio has failed.

I would appreciate if someone could help me resolve the issue as detailed below.

Thanks,
Pradip Muhuri

No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: https://www.latex-project.org/get/

  If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex()

  Otherwise consider MiKTeX on Windows - http://miktex.org

  MacTeX on macOS - https://tug.org/mactex/
