"plot.new()中的错误:图形边距太大" [英] "Error in plot.new() : figure margins too large"

问题描述

在R中，遇到如下运行错误:

In R, I met a running error as follows:

> png("p3_sa_para.png", 4, 2)
> par(mfrow=c(1,2))
> plot(c(1:10), ylab="Beta",xlab="Iteration")
Error in plot.new() : figure margins too large
> plot(c(1:10), ylab="Gamma",xlab="Iteration")
Error in plot.new() : figure margins too large
> dev.off()
X11cairo 
       2 

我已经将图像尺寸缩小为4乘2，为什么它仍然抱怨图边距太大"?如何使用png解决此问题?

I have already made the image size small to be 4 by 2, why it still complains "figure margins too large"? How can I solve this problem with png?

奇怪的是，如果我将png更改为pdf，那么它将起作用.我也想知道为什么吗?

It is strange that if I change png to pdf, then it will work. I also wonder why?

感谢和问候！

推荐答案

png()函数使用的是像素而不是英寸，因此请尝试使用类似的

The png() function uses pixels not inches, so try something like

png("p3_sa_para.png", 640, 480)

回答第二个问题，是的，pdf()使用英寸，因为矢量图形格式没有像素的概念. help(png)和help(pdf)功能是您的朋友.

And to answer your second question, yes, pdf() uses inches because a vector-graphics format has no notion of pixels. The help(png) and help(pdf) functions are your friends.
