Error in process_file(input) :
Quitting from lines 81-87: Error in
getMetricsFromLatex(TeXMetrics) :
TeX was unable to calculate metrics for the following string
or character:

m

Common reasons for failure include:
* The string contains a character which is special to LaTeX unless
escaped properly, such as % or $.
* The string makes use of LaTeX commands provided by a package and
the tikzDevice was not told to load the package.

The contents of the LaTeX log of the aborted run have been printed
above,
it may contain additional details as to why the metric calculation
failed.

Hi,

I tried using knitr with RStudio 0.96.71 on Windows 7 with MikTex 2.9.
I was trying to run the knitr-manual.Rnw file and just pressed Compile
PDF. I got the error above at line 81. See below for the rest of the
log. Could you please tell me what is going on? Is this a problem with
MikTex? I updated MikTex itself and all the packages in it, restarted
RStudio, and it still won't work. I would appreciate any help you can
provide.

Thank you!

Nicolae

This may not be easy to diagnose. It is a problem of tikzDevice; the
first thing to check is the output of:

library(tikzDevice)

I guess I know the reason now: you need to install the tikz package
for LaTeX; I'm not sure how it is called in MikTeX (should be "pgf").
So open the MikTeX package manager, and install pgf. Let me know if
this solves the problem.

Dear Yihui,

thanks for the hint, indeed pgf was not installed.

but the problem is not solved with 'pgf' installation.

reading here : https://groups.google.com/forum/#!msg/tikzdevice/x8RsfdhAepk/xUNPDj0Nj9IJ

i also installed 'preview'. it seems not sufficient neither.

any other idea ? I'll keep investigating

thanks anyway

Pascal

Are you sure you have other packages in knitr-manual.Rnw installed as
well? You can check by, e.g.

kpsewhich tikz.sty
kpsewhich mathpazo.sty

in the command window (Start->Run->cmd).

The tikzDevice package requires some LaTeX expertise to use, and the
knitr manual is probably a too complicated document to start with. If
you want to try tikz with knitr, you can start with a minimal example
like

\documentclass{article}
\begin{document}
<<test, dev='tikz'>>=
plot(1)
@
\end{document}

Just for the record, I solve this problem by removing preview.sty from auctex and using the latest from CTAN (use kpeewhich preview.sty to determine whether this is an issue)  Running a diff the only difference between the two files is that the ctan version has (i) a version; and (ii) a differently formatted date (/ versus -).

Hello Pascal,

 This error message occurs when there's a mistake in the LaTeX code.

Are you sure the "m" in this line is correct ? : 

 \node[inner sep=0pt, outer sep=0pt, scale=1.07999997138977] (TeX) { m}

I have the same problem as Nicolae.

my version of R studio is 0.96.304.

any hints on what could be going wrong ?

below are some outputs.

Hello,
@Rasmus, could you please be more specific about how you updated the
preview.sty pacakge in auctex. I'm having a hell of a time solving this problem.
