Resources to convert from SVG to RGML...

Helped by https://davetang.org/muse/2019/02/22/importing-vector-images-into-r/

So the best workflow, I have is SVG to EPS (encapsulated post script) through illustrator
EPS to RGML through PostScriptTrace
In this way icons can be used in images in R using the grid package...

The RGML format is specific to the grImport package. It is a very simple graphics format that describes an image in terms that the R graphics system can understand. It will be described in more detail in later sections. ... The RGML formatin this example is roughly a one-to-one translation of the PostScript code.16 Apr 2009
