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 Duncan From: Daniel Haugstvedt [mailto:daniel.haugstv...@gmail.com] Sent: Monday, 23 December 2013 20:10 To: Duncan Mackay Cc: John Kane; R Subject: Re: [R] Knitr, ggplot and consistent fonts 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. \documentclass{article} \begin{document} <<setup, include=FALSE, cache=FALSE>>= library(knitr) library(ggplot2) @ \title{Knitr and ggplot2} \author{Daniel Haugstvedt} \maketitle 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. <<plot-figHeight, echo=FALSE, fig.height=2.5, fig.cap="Density plot with no fig.width argument", results='hide', fig.pos='ht'>>= df = data.frame(x = rnorm(100), y = 1:100) ggplot(df, aes(x = x)) + geom_histogram(aes(y = ..density..), binwidth = 1, colour = "black", fill = "white") + xlab("Improvement, %") + ylab("Density") + theme_classic() @ <<plot-figWidth, echo=FALSE, fig.height=2.5, fig.width = 3, fig.cap="Density plot with fig.width=3", fig.pos='ht'>>= ggplot(df, aes(x = x)) + geom_histogram(aes(y = ..density..), binwidth = 1, colour = "black", fill = "white") + xlab("Improvement, %") + ylab("Density") + theme_classic() @ <<plot-figOutWidthBig, echo=FALSE, fig.height=2.5, out.width = "12cm", fig.cap="Density plot with out.width=12cm", fig.pos='ht'>>= ggplot(df, aes(x = x)) + geom_histogram(aes(y = ..density..), binwidth = 1, colour = "black", fill = "white") + xlab("Improvement, %") + ylab("Density") + theme_classic() @ <<plot-figOutWidthSmall, echo=FALSE, fig.height=2.5, out.width = "8cm", fig.cap="Density plot with out.width=8cm", fig.pos='ht'>>= ggplot(df, aes(x = x)) + geom_histogram(aes(y = ..density..), binwidth = 1, colour = "black", fill = "white") + xlab("Improvement, %") + ylab("Density") + theme_classic() @ \end{document} On Sun, Dec 22, 2013 at 11:59 PM, Duncan Mackay <dulca...@bigpond.com> wrote: Hi Daniel I tried it in Sweave after modifying it for Sweave and a similar thing for Latex but R crashed.

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.
