Assuming you are on a Windows OS, you can alternatively create the graph using the showtext package.

library(showtext)
## add the Arial font
font.add("Arial", regular = "arial.ttf",
    bold = "arialbd.ttf", italic = "ariali.ttf", bolditalic = "arialbi.ttf")

setEPS()
postscript("some_graph.eps")
showtext.begin() ## call this function after opening a device

ggplot() + geom_point(aes(x=xvar, y=yvar)) +
    theme_minimal(base_family = "Arial")

dev.off()

The drawback is that you cannot use the ggsave() function, but instead call the device function by yourself.

For the usage of the showtext package, a README is given at https://github.com/yixuan/showtext.
