从 R 创建可编辑图 [英] Create Editable plots from R

问题描述

我正在 R 中创建一系列图(我使用的是 ggplot2，但这不是必需的)并且我希望能够保存我的输出，以便我可以对其进行编辑以供进一步使用，例如，我可能想要移动图例，或调整颜色等.我已经看到 ggplot2 有一个保存命令，但似乎生成 pdf 或位图，这两者都不是特别可编辑的

I'm creating a series of plots in R (I'm using ggplot2, but that's not essential) and I want to be able to save my output so I can then edit it for furthur use, For instance, I might want to move legends about, or adjust colours etc. I have seen that ggplot2 has a save command but that seems to produce pdf's or bitmaps, neither of which are particularly editable

其他人是怎么做到的?有什么好主意吗?

How do other people do this ? Any good ideas ?

这是一些用于生成示例图的示例代码；

Here's some sample code to produce a sample plot;

library(ggplot2)
dataframe<-data.frame(fac=factor(c(1:4)),data1=rnorm(400,100,sd=15))
dataframe$data2<-dataframe$data1*c(0.25,0.5,0.75,1)
dataframe
testplot<-qplot(x=fac, y=data2,data=dataframe, colour=fac, geom=c("boxplot", "jitter"))
testplot

谢谢

保罗.

推荐答案

感谢您的回答，我已经解决了这个问题，在我朋友 Google 的帮助下，我找到了 Cairo 包，允许创建 svg 文件，然后我可以在 Inkscape.

Thanks for the answers, I've played around with this, and after some help from my friend Google I found the Cairo package, which allows creation of svg files, I can then edit these in Inkscape.

library(Cairo)
Cairo(600,600,file="testplot.svg",type="svg",bg="transparent",pointsize=8, units="px",dpi=400)
testplot
dev.off()
Cairo(1200,1200,file="testplot12200.png",type="png",bg="transparent",pointsize=12, units="px",dpi=200)
testplot
dev.off()

现在我只需要在编写文件之前尝试各种设置，以使我的情节尽可能好.

Now I just have to play around with the various settings to get my plot as good as it can be before writing the file.
