无法将ggplot另存为eps [英] Cannot save ggplot as eps

问题描述

我已阅读此和此，但 不能em> .

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") 

我不断收到错误

grDevices :: postscript(...，onefile = FALSE，horizo​​ntal = FALSE，:中的错误:无法打开文件'name.eps'

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

为什么我不能做这个工作?我已经看到建议说嘿，就做...

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()

但是我什至无法保存原始的.eps文件.

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

推荐答案

首先，您的代码中有错误.应该是:

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()

(请注意 aes ).

现在，要将图另存为 eps ，您必须在 ggsave 中使用选项 device = eps :

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

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