Hi Dan
I think you still have problems with embedded characters or some
problems
in
char code page conversion or the like.
Not knowing knitr but Sweave I cobbled the figures manually and ran the
sweave file to produce the latex file.
Latex was consistently stopping at the \caption and \ref functions
I tried to see what was happening I added hyperref & when I copied the
text
to hyperref latex bailed up
I tried a minimal latex file without problems
I put the \title etc in the preamble. Some compilers need this

I am really sorry for posting a non-working example. It is running when
I
cut the code from my previous mail into a clean session in RStudio
(OSX).
However, I suspect that you are right. I did cut and paste some code
from
a
forum yesterday which had characters that had to be replaced. I gave
emacs a
try, but could not find the problem there either.
The code below was pasted though textEdit and converted to plain text.
I
hope this takes care of any embedded characters.

There are four plots in this article. Figure \ref{fig:plot-figHeight}
uses
the argument fig.height=2.5 while Figures \ref{fig:plot-figWidth}
used both fig.height=2.5 and fig.width=3. The later option makes the
font
too big.
An alternative approach is used in Figures
\ref{fig:plot-figOutWidthBig}
and
\ref{fig:plot-figOutWidthSmall}. There the argument out.width is set
to
12 and 8 cm respectively. This stops the problem of excessively large
fonts
for figures with smaller width, but there is still no consistency
across plots in terms o font size.

Hi Daniel
I tried it in Sweave after modifying it for Sweave and a similar thing
for
Latex but R crashed.
I think there is an embedded character/s before the first chunk and in
the
first chunk.

Hi Daniel,
For some reason I cannot get your example to work. The problem is in
the
code chunk but I have no idea what is happening. The code is running
perfectly in R, itself but LaTeX seems to be choking when it hits the
first
ggplot statement, that is the one in <<plot-figHeight>>=
The message I am getting is: "Missing $ inserted <inserted text> $
ggplot(df, aes(x=x)) = geom_" and my knowledge of LateX is not enough
to
figure out the problem.
I tried stripping out most of the LaTeX specific verbiage in the code
chunk
and running the code in LyX which I use rather than plain vanilla LaTeX
and
I still cannot get it to work. It is almost as if there is some hidden
character in the in that piece of code since I can duplicate the code
myself
and I even pasted in most of the geom_histogram code into my code chunk
and
it runs.

Dear R-help
I am using Knitr and ggplot to draft an article and have now started
to improve on the layout and graphics. So far I have not been able to
maintain the same font size for labels in all my figures.
My goal is to be able to change the width of the figures while
maintaining the same font. This works for the height parameter
(example not included).
In the true document I also use tikz, but the problem can be
reproduced without it.
I know the question is very specific, but my understanding is that
this combination of packages is common. (They are really great. Keep
up the good work.) There has to be others facing the same problem and
someone must have found a nice solution.
Additional attempts from my side which failed are not included in the
example. I have tested the Google results i could find without any
luck.
Cheers
Daniel
PS. I know the example plots could have been smaller, but they just
became too ugly for me
