Hi
Do you mean you want to reduce *system requirements* ? I'm not sure you
have many options. Looking at the plantuml output format options, there
is ...
png via 'png', which requires libpng
svg via 'grImport2', which requires 'rsvg', which requires librsvg2
eps via 'grImport', which requires ghostscript
... and a number of other formats that cannot be read directly into R AFAIK.
The only option that does not require dependencies looks like the "txt"
format, which you could read in with readLines(), but I'm not sure you
want an ASCII art version :)

Hi
I have a package, which plots from the plantuml syntax (https://plantuml.com)
graphs via a knitr engine, into a file, or into a graphics device
(https://github.com/rkrug/plantuml).
I am using at the moment grImport for the eps import, but would like to cut
down on dependencies.
Is there a way of bringing graphics files (png, sag, eps, …) into a graphics
device in R?
Thanks,
Rainer
