考虑以下代码:

library(lattice)
m <- matrix(1:16, nrow=4)
splom(m, panel=function(x, y, ...) {
  panel.xyplot(x, y, ...)
  panel.smooth(x, y, ...) ## this line doesn't seem to work
})

调用它会给我错误:

Error in grid.Call.graphics(L_downviewport, name$name, strict) : 
  Viewport 'plot_01.panel.1.1.off.vp' was not found

我究竟做错了什么?这是一个错误吗?如何在格 splom 中叠加平滑线?

panel.smooth实际上,是一个函数,graphics而不是lattice; 不幸的是,该名称具有误导性(我认为它是lattice面板功能系列的一部分,但我错了)。

panel.loess可能是首选。
