Re: [R] Knitr, ggplot and consistent fonts
I believe you are right. We thank either Gmail or [[alternative HTML
version deleted]] for this. I think showNonASCII() is just irrelevant
here and pulling us to the wrong direction.
It is not reliable to paste code into Email due to the potentially
wrong text wrapping. Please consider an email attachment (not sure if
an Rnw document can get through), or a Github gist, or pastebin
instead, e.g. https://gist.github.com/yihui/8105762 Or ask on SO:
http://stackoverflow.com/questions/tagged/r
Now let's move back to the original question, to which I have no solution.

Re: [R] Knitr, ggplot and consistent fonts
Thanks, I was not getting anything when I printed the x and so thought I was
doing something wrong. Instead I just didn't seem to have a non-ASCII
character.

"returned invisibly" means that the result is returned with a flag set
so it won't automatically print. If you want to print it, you need to
ask. So any of these will work to see the result:
x <- showNonASCII( )
x
or
print(showNonASCII( ))
or even (though this is one some of us don't like, it still works...)
(showNonASCII( ))

You get that error because you're using double quotes around a string

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

Re: [R] Knitr, ggplot and consistent fonts
Hi, chiming in.
Pasted the code in R studio and the format parser wouldn't mark the R code
chunks. It was because there were line breaks in the middle of chunk
options tags. Couldn't test if removing line breaks works, but maybe
that's the source of the problem?

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

An alternative approach is used in Figures

12 and 8 cm respectively. This stops the problem of excessively large

Re: [R] Knitr, ggplot and consistent fonts
Thanks Richard. I did not realise such a function existed.
Assuming I am using it correctly I do get an error though not where I was
expecting it. Anyway the code below returns an error
library(tools)
showNonASCII("ggplot(df, aes(x = x)) + geom_histogram(aes(y = ..density..)),
binwidth = 1, colour = "black", fill = "white")")
Results
Error: unexpected symbol in:
"showNonASCII("ggplot(df, aes(x = x)) + geom_histogram(aes(y = ..density..)),
binwidth = 1, colour = "black"

Does not seem to be. I 'think' I removed all the line breaks and it still is
not compiling. Thanks for the suggestion. I had not bothered to paste the

have noticed it.

Hi, chiming in.
Pasted the code in R studio and the format parser wouldn't mark the R code
chunks. It was because there were line breaks in the middle of chunk options
tags. Couldn't test if removing line breaks works, but maybe that's the source
of the problem?

Re: [R] Knitr, ggplot and consistent fonts
Same result here with the same error message mentioned in my first post. I
tried it in Texmaker which is my usual Latex editor, not that I do much in
Latex, and then tried it in RStudio and it is still choking.
Interestingly EMACS will process it and produce a pdf but it simply produces.
It also provides this warning: : Latex Warning; Reference 'fig:plot-figheight'

Re: [R] Knitr, ggplot and consistent fonts
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

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 <>=
The message I am getting is: "Missing $ inserted $
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.

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.

Re: [R] Knitr, ggplot and consistent fonts
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 <>=
The message I am getting is: "Missing $ inserted $ 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.

Re: [R] Knitr, ggplot and consistent fonts
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 <>=
The message I am getting is: "Missing $ inserted $ 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.
