R knitr error 41 when producing pdf (windows)

Question

I have been trying to make a simple PDF using the "Knit PDF" functionality from RStudio.

Every time I try to convert the sample doc to a PDF I get the following message:

|............. | 20%

ordinary text without R code

|.......................... | 40%

label: unnamed-chunk-1

|....................................... | 60%

ordinary text without R code

|.................................................... | 80%

label: unnamed-chunk-2 (with options)

List of 1

$ echo: logi FALSE

|.................................................................| 100%

ordinary text without R code

pandoc.exe: pdflatex not found. pdflatex is needed for pdf output.

Error: pandoc document conversion failed with error 41

In addition: Warning message:

Execution halted

No TeX installation detected (TeX is required to create PDF output). You should install a recommended TeX distribution for your platform:

Windows: MiKTeX (Complete) - http://miktex.org/2.9/setup (NOTE: Be sure to download the Complete rather than Basic installation)

Mac OS X: TexLive 2013 (Full) - http://tug.org/mactex/ (NOTE: Download with Safari rather than Chrome strongly recommended)

Linux: Use system package manager

I edited out the path locations on my PC as well as the intended title of the PDF (changing them with "PATH1", "PATH2", and "DOCTITLE" where appropriate.)

I have used the link to download MikTex multiple times to multiple locations, I have tried using ProTex as some others have had success doing. I have tried adding the bin of MikTex to the environment but no matter what, it seems that R is unable to find Tex. Most of the advice available is for OSX, and I have tried adapting those solutions for windows to no avail.

Answer 1

@Matty R, after getting that error I restarted Rstudio, and then it asked me to instally packages like "upquote" using MikTex Package Manager, after three or four packages installation I got the pdf file created.
