添加表格(对齐的文本块)以在R中绘图 [英] Add table (aligned text blocks) to plot in R

问题描述

我想在 R 中的图中添加一张小表(例如，作为图例).我想到的是这样的东西:

I'd like to add a small table (for example as a legend) to a plot in R. I think of something like:

t <- wantedTableMethod(
  row("param1", "param2", "param3", "param4")
  , row(value11, value12, value13, cell(value14, adj=0))
  , row(value21, value22, value23, value24)
  , row(value31, value32, value33, cell(value34, adj=1))
  border = F
)
plot(1,1)
legend("topleft", t)

列的所有值应具有相同的偏移量.在 R 中是否可能发生这种情况，还是我需要手动对齐每个值?

All values of a column should have the same offset. Is something like this possible in R, or do I need to align each value manually?

推荐答案

plotrix软件包具有addtable2plot函数，您可以将data.frame或matrix传递给

The plotrix package has a addtable2plot function you can pass a data.frame or matrix to

使用帮助页面中的示例

library(plotrix)
testdf<-data.frame(Before=c(10,7,5,9),During=c(8,6,2,5),After=c(5,3,4,3))
 rownames(testdf)<-c("Red","Green","Blue","Lightblue")
 barp(testdf,main="Test addtable2plot",ylab="Value",
  names.arg=colnames(testdf),col=2:5)
 # show most of the options
 addtable2plot(0.7 ,8,testdf,bty="o",display.rownames=TRUE,hlines=TRUE,
  vlines=TRUE,title="The table")

它旨在与legend尽可能相似地工作.

It is designed to work as similarly to legend as possible.
