RMarkdown: Not able to knit to pdf - r

I have been using Rmarkdown for some months but suddenly I can't knit to pdf any longer, I installed the latest version of rstudio and tinytex, Yet it's not building pdf. What else can I do?.
Below is the error message:
! Package inputenc Error: Unicode character ^^N (U+000E)
(inputenc) not set up for use with LaTeX.
Try other LaTeX engines instead (e.g., xelatex) if you are using pdflatex. See https://bookdown.org/yihui/rmarkdown-cookbook/latex-unicode.html
Error: LaTeX failed to compile Introduction-to-R-for-statistical-computing.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See Introduction-to-R-for-statistical-computing.log for more info.
Execution halted

After I tried severally, I came across this tinytex::reinstall_tinytex() from Why "Knit to pdf" in RMarkdown throws error? today.
It works for me perfectly. The pdf was built with all my equations written in tex. Also document was knitted in word with all the statistical models. Thanks so much.

R markdown themes not knitting

Currently I'm working on automating a project. Problem: The program is failing to knit because of the following code:
output:
powerpoint_presentation:
reference_doc: ref.pptx
The error code states:
Could not find shape for Powerpoint content
Error: pandoc document conversion failed with error 63

When I put my presentation into Google Slides, the theme works without a problem. Any ideas on how to fix this?

knitr Minimal Demo not compiling correctly

Hi knitr experts: I cannot for the life of me figure out how to compile the knitr Miminal Demo .Rnw document correctly. When I download and run Yihui's Minimal Demo of knitr .Rnw file (link), the document compiles but incorrectly handles the R chunks:
I changed nothing, just opened and compiled. Help welcome. As an aside, would very much appreciate tips on whether this is how I should be going about adding R code into a latex template that UT-Austin requires for dissertation publication. Thanks.
I can reproduce your PDF file when using Sweave instead of knitr for translating the .Rnw file. When switching to knitr via the RStudio options (c.f. https://support.rstudio.com/hc/en-us/articles/200532247), I get an error message and no PDF, which probably reproduces #r2evans' results in the comments. I also get a warning message that line 19 is Sweave specific (\SweaveOpts{concordance=TRUE}). Removing that line, the file processes with knitr correctly producing

LaTeX Error: Option clash for package xcolor in Rmarkdown for pdfOutput

Hopefully, this isn't a duplicate post. I took a look at some of the relevant questions that already exist and either it has to do with latex rather than r-markdown or it has to do with the "beamer" type output.
My program uses the package knitr. If I try to format my kable tables in latex format, I get the error message "! LaTeX Error: Option clash for package xcolor". Is there a workaround for r-markdown? What's specifically causing the clash?

Rmarkdown, Rstudio: pandoc.exe: Error producing PDF from TeX source

I am trying to render a pdf document with the knit pdf button in RStudio, but I keep on getting this error:
! pdfTeX error (font expansion): auto expansion is only possible with scalable
fonts.
\AtBegShi#Output ...ipout \box \AtBeginShipoutBox
\fi \fi
l.167
pandoc.exe: Error producing PDF from TeX source
Error: pandoc document conversion failed with error 43
I know there is a lot be found on the internet regarding error 43, but non of them helped me.
Does anyone know what it means exactly and where I can find the solution? It's peculiar because a few hours ago I had the same error but the rendering went well after adding this in my code:
Sys.setenv(PATH = paste(Sys.getenv("PATH"), "C:\\Program Files\\MiKTeX 2.9\\miktex\\bin\\x64\\", sep=.Platform$path.sep))
But now the error is back
EDIT
when trying a minimal example:
---
title: "test"
output: pdf_document
---
```{r results="asis"}
library(stargazer)
c1 <- c("test1","test1","test2","test2")
c2 <- c(1,2,3,4)
data_object <- as.data.frame(cbind(c1,c2))
names(data_object) <- c("test","test2")
stargazer(data_object,summary=FALSE,rownames=FALSE,type="html")
```
The error it gives is:
!pdfTeX error: pdflatex (file ec-lmr10): Font ec-lmr10 at 600 not found
==> Fatal error occurred, no output PDF file produced!
Trying to make PK font ec-lmr10 at 600 DPI...
Running miktex-makemf.exe...
miktex-makemf: The ec-lmr source file could not be found.
miktex-makepk: The application file ttf2pk.exe could not be found.
pandoc.exe: Error producing PDF from TeX source
Error: pandoc document conversion failed with error 43
This is a different error, but still a 43 one. I checked it, but the font ec-lmr10 file is on the system. Somehow it can't be found.
The problem you have is a font related one. When you knit a PDF, knitr uses LaTeX and you have to know that "fonts" of LaTeX are not like the standard ones.
To solve your problem try to add the latin model font family by loading the package (at the very top):
\usepackage{lmodern}
For more detailed informations about how and where insert this piece of code in your document, have a look here.
This package allows you to have scalable fonts; not all fonts of all (font) packages are to so.
I think, but I might be wrong, because first versions of TeX and LaTeX were designed to work with METAFONT.
Edit
Your code works well for me, it does not produce any error. My idea is that happens because I have a complete Tex live distribution on my Mac (MacTeX). At this point I suppose that the problem relies on some packages that the r packages you use (like stargazer) use and you (we) do not know and won't (unless we analyze the code of course).
At this point my suggestion is to download a complete TeX distribution so you will be sure that any error related to PDF output is no related to the underlying tool that Studio uses to produce such PDFs (say, LaTeX).
You can find a complete LaTeX distribution for Mac and for Windows.

Inputenc/Pandoc error when knit to Pdf on Rstudio Version 0.98.994

I am getting an error to knit a Rmd document to pdf. Here is the part of the code causing the error.
```{r chunk5 ,echo=F}
hypoconf<-function(z){if(z=="dose"){
cat(paste(as.character(1),"\b. If there is no difference in
tooth growth for" ,z, "of",as.character(20),"and"
as.character(10),"the probability of seeing the
observed or more extreme outcome is", as.character(30),"percent."))
cat("\n\n")
}
hypoconf("dose")
```
This throws the following error when knitting to pdf.
output file: report2.knit.md
pandoc: Error producing PDF from TeX source.
! Package inputenc Error: Keyboard character used is undefined
(inputenc) in inputencoding `utf8'.
See the inputenc package documentation for explanation.
Type H <return> for immediate help.
...
l.260 \end{verbatim}
Try running pandoc with --latex-engine=xelatex.
Error: pandoc document conversion failed with error 43
Execution halted
I do not get the same error when I knit to html instead. Also, I have figured out the sources of error are the backspace \b and the newline \n characters in my code. But I cannot find a way to get around this.
Using the tidy =F option in the r-code chunk seems to have removed the error for me.
