在绘图中添加矩阵？

Is there anyway to add a table to a plot. Suppose that I have the plot below:

无论如何都要在剧情中添加一张桌子。假设我有以下情节:

curve(dnorm, -3, +4)

Now I like to add a matrix beneath the plot:

现在我想在情节下面添加一个矩阵:

testMat <- matrix(1:20, ncol = 5)

My goal? I'm writing a plot function that not only does create a plot, but it also shows a matrix including the information I'm interested in underneath the plot.

我的目标?我正在编写一个绘图函数,它不仅创建了一个绘图,而且还显示了一个矩阵,其中包含我对绘图下方感兴趣的信息。

Please see the attached picture to see what I mean. I really appreciate your help.

请参阅附图了解我的意思。我非常感谢你的帮助。

There are probably better ways to do this, but one option might be to use one of the packages that "plots" matrices and data frames, like the "gplots" package.

可能有更好的方法来做到这一点,但一种选择可能是使用“绘制”矩阵和数据框的一个包,如“gplots”包。

Here is a very bare example (you can probably customize this for much finer control over the final layout).

这是一个非常简单的例子(你可以自定义它,以便对最终布局进行更精细的控制)。

# Some sample data
testMat <- matrix(1:20, ncol = 5)
testMatDF <- as.data.frame(testMat)
names(testMatDF) <- c("Hey there", "Column 2", 
                      "Some * Symbols", "And ^ More", 
                      "Final Column")
rownames(testMatDF) <- paste("Group", 1:4)

# Load the package
library(gplots)
# Set par for plotting a three-row plot
par(mfrow = c(3, 1))
curve(dnorm, -3, +4)
textplot(testMat)
textplot(testMatDF)

The result:

You can also use layout() instead of par(mfrow...) if you want to get a little bit more creative with the placement of your plots. For example:

如果您希望通过放置图表来获得更多创意,也可以使用layout()而不是par(mfrow ...)。例如:

layout(matrix(c(1, 1, 2, 3, 3, 3), 
              2, 3, byrow = TRUE))
curve(dnorm, -3, +4)
textplot(testMat)
textplot(testMatDF)

Package plotrix provides function addtable2plot.

Package plotrix提供addtable2plot功能。

Example from the help file:

帮助文件中的示例:

library(plotrix)
testdf<-data.frame(Before=c(10,7,5),During=c(8,6,2),After=c(5,3,4))
rownames(testdf)<-c("Red","Green","Blue")
barp(testdf,main="Test addtable2plot",ylab="Value",
     names.arg=colnames(testdf),col=2:4)
# show most of the options
addtable2plot(2,8,testdf,bty="o",display.rownames=TRUE,hlines=TRUE,
              title="The table")

Edit: Put the table in a new plot to place it underneath your plot.

编辑:将表格放入新图表中,将其放置在图表下方。

library(plotrix)

layout(matrix(c(1,2), 2, 1, byrow = TRUE),
       widths=c(1,1), heights=c(2,1))


testdf<-data.frame(Before=c(10,7,5),During=c(8,6,2),After=c(5,3,4))
rownames(testdf)<-c("Red","Green","Blue")
barp(testdf,main="Test addtable2plot",ylab="Value",
     names.arg=colnames(testdf),col=2:4)

plot.new()
addtable2plot(0,0,testdf,bty="o",display.rownames=TRUE,hlines=TRUE,
              title="The table")
