与John Fox的效果图进行grid.arrange [英] grid.arrange with John Fox's effects plots

问题描述

我想在一个窗口中将多个效果图与效果包组合在一起，但是不知道是否有一种简便的方法.

I'd like to combine multiple effect plots in one window with the effects package, but don't know if there is an easy way to do so.

这是一个不起作用的示例:

Here's an example that doesn't work:

d1 <-data.frame(x1=rnorm(100,0:10),y1=rnorm(100,0:10),x2=rnorm(100,0:10),y2=rnorm(100,0:10))
require(effects)
require(gridExtra)
plot1 <- plot(allEffects(mod=lm(y1~x1,d1)))
plot2 <- plot(allEffects(mod=lm(y2~x2,d1)))
grid.arrange(plot1,plot2,ncol=2)

推荐答案

我认为您需要收集allEffects组件的值，然后将它们绘制为效果列表".在我看来，该图是基础图形，但是如果您遵循类函数路径(或者如果您阅读:?plot.efflist)

I think you need to collect the values of allEffects components and then plot them as an 'efflist'. It looked to me that the plotting was base-graphics, but it is in fact 'lattice' if you follow the class-function trail (or if you read: ?plot.efflist )

尝试一下:

ef1 <-allEffects(mod=lm(y1~x1,d1))[[1]]
ef2 <- allEffects(mod=lm(y2~x2,d1))[[1]]
elist <- list( ef1, ef2 )
class(elist) <- "efflist"
plot(elist, col=2)
