Hello, since a couple of days I'm trying hard to elicit a certain thing out of the Sweave function of R. Unfortunately I'm quite unsuccessful.
It's only about a small, ridiculous minus sign, which does not appear in the final pdf of a latex file, if I try to incorporate the Computer- Modern fonts into the plot. It seems, that R uses different encodings for minus signs, which are put "by hand" and which are plotted from a variable with negative value. ### As a fast example everybody can retrace immediately, there is the nice example of Paul Murrell which can be found at: http://www.stat.auckland.ac.nz/~paul/R/CM/CMR.html Essentially, what I need from this page are the following 4 files for creating my final pdf: http://www.stat.auckland.ac.nz/~paul/R/CM/cmTutorial.Rnw This example needs the according Tex-package and the files for the symbol faces found at: http://www.ctan.org/tex-archive/help/Catalogue/entries/cm-lgc.html http://www.stat.auckland.ac.nz/~paul/R/CM/cmsyase.afm http://www.stat.auckland.ac.nz/~paul/R/CM/cmsyase.pfb ### Creating the tex-file with R CMD Sweave cmTutorial.Rnw (if the 'lattice' package is not loaded immediately then type a library(lattice) in front of the 'print(<<latticeCode>>)' ) and compiling it with pdflatex cmTutorial.tex yields a perfect plot. BUT, if minus signs appear in the plot, it does not work poperly anymore! Just change the endpoints in the 'histogram' function to 'c(-59.5, 76.5)' ( instead of 'c(59.5, 76.5)' ) and run the two upper commands again. Then, I see a minus sign in the file 'cmTutorial-latticeShow.pdf' but NOT in the 'cmTutorial.pdf'. However, putting sth. like 'mtext("-3.14...",1,-2)' somewhere, I will see a nice minus sign also in the final plot. But it will look different compared to the minus which I can see in 'cmTutorial-latticeShow.pdf'. ### Can anybody explain me, how to get rid of this problem? How can pdflatex change something in the included pdf?
