Hi Yihui, Hi Duncan, I corrected my typo. Unfortunately knitr did not find my plots in the directory where they reside which is different from the Rmd document. The documentation of knitr says: base.dir: (NULL) an absolute directory under which the plots are generate root.dir: (NULL) the root directory when evaluating code chunks; if NULL, the directory of the input document will be used
From that description I thought, if the base.dir can be used for writng
plots, it is then also used for reading plots if set? No, it is not. If I set the root directory to the plots/graphics directory will knitr then find my plots? No, it does not. Reading blog posts my thoughts looked not so strange to me, e.g. https://philmikejones.wordpress.com/2015/05/20/set-root-directory-knitr/. Unfortunately, it does not work for me. I am using a RStudio project file. Could it be that this interferes which the knitr options? I tried the solution that Duncan suggested: c_path_plots <- "H:/2017/Analysen/Kundenzufriedenheit/Auswertung/results/graphics `r knitr::include_graphics(file.path(c_path_plots, "email_distribution_pie.png"))` This solution works fine. I will go with it for this project as I have to finish my report soon. I read Hadley's book on bulding R Packages ( https://www.amazon.de/R-Packages-Hadley-Wickham/dp/1491910593) and found it quite complicated and time consuming to build one. Thus I did not try yet to build my own packages. At the end of last week I heard from another library (http://reaktanz.de/R/pckg/roxyPackage/) which shall make building packages much easier. I plan to try that shortly. On my path to become better in analytics using R, I will try to use modules of Rmd files which can then easily be integrated into a Rmd report. I have yet to see how I can include these file into a complete report.

If you do not understand what it means, I strongly recommend you not to set it. Similarly, you set the root_dir option and I don't know why you did it, but it is a typo anyway (should be root.dir).

Hi Yi, many thanks for your reply. Why I do have to se the base.dir option? Cause, to me it is not clear
from
the documentation, where knitr looks for data files and how I can adjust knitr to tell it where to look. base.dir was a try, but did not work. Can you give me a hint where I can find information/documentation on
this
path issue? Kind regards Georg

Hi All, I have to compile a report for the management and decided to use
RMarkdown
and knitr. I compiled all needed plots (using separate R scripts)
before
compiling the report, thus all plots reside in my graphics
directory.
The
RMarkdown report needs to access these files. I have defined
```{r setup, include = FALSE}
knitr::opts_knit$set(
echo = FALSE,
xtable.type = "html",
base.dir = "H:/2017/Analysen/Kundenzufriedenheit/Auswertung",
root_dir = "H:/2017/Analysen/Kundenzufriedenheit/Auswertung",
fig.path = "results/graphics") # relative path required, see
http://yihui.name/knitr/options
```
and then referenced my plot using
<img src = "email_distribution_pie.png"></img>
because I want to be able to customize the plotting attributes.
But that fails with the message "pandoc.exe: Could not fetch
email_distribution_pie.png".
If I give it the absolute path
"H:/2017/Analysen/Kundenzufriedenheit/Auswertung/results/
graphics/email_distribution_pie.png"
it works fine as well if I copy the plot into the directory where
the
report.RMD file resides. How can I tell knitr to fetch the ready-made plots from the graphics directory? Kind regards Georg
