Works fine on mine, but I did notice it throws a warning: maybe this is the problem. Does

R"qplot(data=data.frame(x=rnorm(100), y=rnorm(100)), x=x, y= y) + geom_smooth(method='loess')"

work? Also, does

R"warning('test')"

work?

[jotwin]

warning works, your other suggestion does not

julia> R"warning('test')"

Hmm, that ruins that theory then. What OS & version (i.e. output of lsb_release -a)?

@jotwin Were you using X11 as the graphical device? Would you try using pdf device?

Does it work without geom_smotth? (i.e., it creates the file a.pdf). How about running the same commands in R? Does it raise a segfault?

[jotwin]

No problems in R, or in RCall without geom_smooth
