VennDiagram有问题吗? [英] Problems with VennDiagram?

问题描述

我成功地使用了这里给出的配方.但是，在过去的几天中，这似乎不起作用.我的sessionInfo()看起来如下:

I have used the recipe given here with a lot of success. However, for past few days this does not seem to work. My sessionInfo() looks as follows:

R version 2.15.2 (2012-10-26)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] grid      stats     graphics  grDevices utils     datasets  methods   base     

other attached packages:
[1] VennDiagram_1.5.1

loaded via a namespace (and not attached):
[1] tools_2.15.2 

我尝试了以下操作，但未产生任何结果:

I tried the following, and did not produce any result:

 require(VennDiagram)

 venn.diagram(list(B = 1:1800, A = 1571:2020),fill = c("red", "green"), alpha = c(0.5, 0.5), cex = 2,cat.fontface = 4,lty =2, fontfamily =3, filename = "trial2.emf")

但是没有产生任何结果.

But did not produce any result.

我做错什么了吗?

推荐答案

一种解决方法是使用png()或pdf()保存图.我们首先确认可以使用grid.draw()在屏幕上绘制该图:

One work-around is to use png() or pdf() to save the plot. We first confirm that we can draw the plot onscreen using grid.draw():

library(VennDiagram)
temp <- venn.diagram(list(B = 1:1800, A = 1571:2020),
    fill = c("red", "green"), alpha = c(0.5, 0.5), cex = 2,cat.fontface = 4,
    lty =2, fontfamily =3, filename = NULL)
grid.draw(temp)

已经确认，要保存它，我们要做的就是在pdf()和dev.off()

Having confirmed that, all we need to do to save it is repeat the grid.draw() between pdf() and dev.off()

library(grDevices)

pdf(file="venn.pdf")
    grid.draw(temp)
dev.off()

pdf()和png()如其帮助文件中所述，具有用于控制图像尺寸之类的参数，从而改善了对图像质量的控制.

As described in their help files, pdf() and png() have arguments for controlling things like the size of the image, improving control over image quality.
