Cannot save ggplot as eps

I've read this and this but cannot make it work. 

vDF <- data.frame(v = rnorm(50,1,40))
g <- ggplot(vDF, aes(x = vDF)) + geom_histogram()
ggsave(g, file="name.eps")

I keep getting the error

Error in grDevices::postscript(..., onefile = FALSE, horizontal = FALSE, : cannot open file 'name.eps'

Why can't I make this work? I've see advice saying 'hey just do... 

setEPS()
postscript("whatever.eps")
plot(rnorm(100), main="Hey Some Data")
dev.off()

But I can't even save the original .eps file in the first place.

None of the above works for me. I had to specify the font in the ggsave()

    ggsave(filename = "fig1.eps", plot=fig1,family="Times")

Discovered how to do this properly

ggplot2::ggsave(filename = "foo.eps",
                plot = foo,
                device = cairo_ps)

specifying cairo_ps for the device is the key

First, there's an error in your code. It should be:

vDF <- data.frame(v = rnorm(50,1,40))
g <- ggplot(vDF, aes(x = v)) + geom_histogram()

(note the aes).

Now, to save the plot as eps, you have to use the option device=eps in ggsave: 

ggsave(g, file="name.eps", device="eps")
