I get "LaTeX Error: File `figure/minimal-boring-plots1' not found." running knitr-minimal.lyx

Question

LyX Version 2.1.1 R version 3.1.0 (2014-04-10) -- "Spring Dance" Platform: x86_64-w64-mingw32/x64 (64-bit) MikTex ver 2.9

I have just installed LyX and cannot get plots in the output. I can get basic knitr examples with no plots to complie to a pdf.

If I View[Ctrl-R] the file knitr-minimal.lyx from within LyX I get the above error message, "LaTeX Error: File `figure/minimal-boring-plots1' not found." with description: " ...\linewidth]{figure/minimal-boring-plots1}

I could not locate the file with any of these extensions: .png,.pdf,.jpg,.mps,.jpeg,.jbig2,.jb2,.PNG,.PDF,.JPG,.JPEG,.JBIG2,.JB2"

However, if I save the knitr-minimal.Rnw file to my R work directory, then run the R script: require(knitr) rnwfile <- "knitr-test.Rnw" knit(rnwfile)

This will produce a TeX file, knitr-minimal.tex, in my work directory, that MikTeX compiles correctly to a pdf with plots included.

I assume I have something setup incorrectly in LyX:(

Any help would be appreciated.

Thanks bob

What version of knitr are you using? If you are using version 1.6, can you try using version 1.5? To do that, do remove.packages(knitr) in R (confirm that it is removed by trying to load it), and then install cran.r-project.org/src/contrib/Archive/knitr/knitr_1.5.tar.gz — scottkosty
Thanks @scottkosty. I was using knitr version 1.6. When I try to install knitr 1.5 and get an error message:> utils:::menuInstallLocal() Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) : cannot open the connection This a problem with our zip program. I'll try to work on it — ouldphart

My bad. The problem was in the setup of LyX. Instead of allowing the default working directory in the LyX setup I choose the one I wanted to use and some combination of LyX, knitr, and laTeX could not deal with that. After I reset the working directory to the temp directory the packages can now communicate and a pdf with plots was produced. Sorry for the inconvenience. bob
