Hi
I am referring to issue https://github.com/rkrug/plantuml/issues/8 in my plantuml package.
A trailing linebreak at the end causes an error in plantuml in my R package. trimming the trailing linbebreak solves the problem.
https://github.com/rkrug/plantuml/commit/6813ee34f6f7c33788aa04fd06558498bb7df988#diff-b97e0eda151de051586a3a6db9e28269L32
https://github.com/rkrug/plantuml/blob/6813ee34f6f7c33788aa04fd06558498bb7df988/R/plantuml.R#L32
I think it is a problem in plantuml, as it was working earlier and it occurs in all different graphs.
