绘图窗口的总标题 [英] Overall Title for Plotting Window

问题描述

如果我在R中创建一个具有m行和n列的绘图窗口，我怎么能给整体图形设置一个主标题？

例如，I可能有三张散点图显示了3所不同学校的GPA和SAT分数之间的关系。我怎样才能给所有三个地块提供一个主标题，例如CA中的3所学校的SAT分数与GPA比较？ 解决方案

我想到的最明显的方法是使用Lattice或ggplot2。这里有一个使用格子的例子：

pre $ library（lattice）
depthgroup <-equal.count（quakes $ depth，number = 3，overlap = 0）
magnitude< -equal.count（地震$ mag，number = 2，overlap = 0）
xyplot（lat_long | depthgroup * magnitude，
data =地震，
main =Fiji Earthquakes，
ylab =latitude，xlab =longitude，
pch =。，
scales = list（x = list （交替= c（1,1,1））），
之间= list（y = 1），
par.strip.text = list（cex = 0.7），
par。设置= list（axis.text = list（cex = 0.7）））


main =参数。

上述示例已从这里。

我没有一个好的ggplot2例子，但是在学习r博客。

一个选项可能是这个例子他们使用ggplot2和

  opts（title =RSS和NINO3.4温度异常\和1980年以来的SATO指数趋势）
  

但是你自然会得到在gg2plot中创建的所有三张图。

我认为你应该可以使用格或ggplot2。

If I create a plotting window in R with m rows and n columns, how can I give the "overall" graphic a main title?

For example, I might have three scatterplots showing the relationship between GPA and SAT score for 3 different schools. How could I give one master title to all three plots, such as, "SAT score vs. GPA for 3 schools in CA"?

解决方案

The most obvious methods that come to my mind are to use either Lattice or ggplot2. Here's an example using lattice:

 library(lattice)
 depthgroup<-equal.count(quakes$depth, number=3, overlap=0)
 magnitude<-equal.count(quakes$mag, number=2, overlap=0)
 xyplot(lat ~ long | depthgroup*magnitude,
 data=quakes,
 main="Fiji Earthquakes",
 ylab="latitude", xlab="longitude",
 pch=".",
 scales=list(x=list(alternating=c(1,1,1))),
 between=list(y=1),
 par.strip.text=list(cex=0.7),
 par.settings=list(axis.text=list(cex=0.7)))

In lattice you would change the main= parameter.

The above example was lifted from here.

I don't have a good ggplot2 example, but there are a metricasston of examples with ggpolot2 over at the learn r blog.

One option might be this example where they use ggplot2 and

opts (title = "RSS and NINO3.4 Temperature Anomalies \nand SATO Index Trends Since 1980")

But you would have to have all three graphs created in gg2plot, naturally.

I think you should be fine with either lattice or ggplot2.
