[R] Paths in knitr

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}
  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 

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 

If I give it the absolute path 
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 

Kind regards
