Running: plot(as.plantuml(list(a = 1, b = 2)))

Produces the following error:

Is there a way to set the -Djava.awt.headless=true option which presumably fixes this?

rkrug commented 6 years ago

You are likely right - I never tried it on a headless computer or one without GUI.

I won’t have time to look at it this week. You could try to run plantuml directly from the command line and see if it works from there? That would help, as I don’t have a Linux computer at hand.

I will see what I can do next week.

Thanks.

Please see commit which adds an argument to plot.plantuml() to allow java options. You can use it as follow:

# to update to that commit
devtools::install_github("rkrug/plantuml", ref = "2a21cdc129848a995cefd2e6031e489c4a4c2fa5")
# 
x <- 5
plot(as.plantuml(x), java_opt = "-Djava.awt.headless=true")

Please let me know if it works.

@rkrug this works now. Thank you. R6 class support would be great : )

rkrug commented 6 years ago

Great.

Could you please file a new issue / feature request for R6 so that they don’t get lost? Thanks.

I myself have never used R6 classes, but at least the idea does not get lost and can be discussed in detail there.
