Figure sizes with pandoc conversion from markdown to docx

I type a report with Rmarkdown in Rstudio. When converting it in html with knitr, there is also a markdown file produced by knitr. I convert this file with pandoc as follows :

pandoc -f markdown -t docx input.md -o output.docx

The output.docx file is nice except for one problem: the sizes of the figures are altered, I need to manually resize the figures in Word. Is there something to do, maybe an option with pandoc, to get the right figures sizes ?

Solution

  • An easy way consists in including a scale factor k in the individual chunk options:

    {r, fig.width=8*k, fig.height=6*k}

    and a variable dpi in the global chunk options:

    opts_chunk$set(dpi = dpi)

    Then you can set the values of dpi and k before knitting the Rmd file in the global environment:

    dpi <<- 96    
k <<- 1

    or you can set them in a chunk in the Rmd file (set k in the first chunk for example).
