Question

例如：

mytheme <- trellis.par.get()
mytheme$strip.border$col = 'grey80'
mytheme$strip.background$col = 'grey80'
mytheme$axis.line$col = 'grey80'
mytheme$axis.text$col = 'grey60'
mytheme$plot.symbol$pch = 20
mytheme$plot.symbol$cex = .5
mytheme$plot.symbol$col = '#7AC5CD'
mytheme$plot.symbol$alpha = .8

l.sc <- update(scatter.lattice, par.settings = mytheme,
               layout = c(3, 2),
               between = list(x = 0.3, y = 0.3))
print(l.sc)

如何将par.settings的默认设置为mytheme？

在 Lattice Multivariate Data Visualization with R 一书中，第131页，作者给出了这个例子：

lattice.options(lattice.theme = standard.theme("pdf"))

但我不知道如何使其适应当前的情况。我试过了：

lattice.options(lattice.theme = mytheme)

它不起作用。

主题可以持久设置（即，它们将影响所有后续绘图直到新的使用trellis.par.set()函数指定了设置：

 trellis.par.set(mytheme) ## mythme is a named list with settings parameters

其中mytheme是一个列表（无需调用trellis.par.get（））：

mytheme <- list()
mytheme$strip.border$col = 'grey80'
mytheme$strip.background$col = 'grey80'
mytheme$axis.line$col = 'grey80'
mytheme$axis.text$col = 'grey60'
mytheme$plot.symbol$pch = 20
mytheme$plot.symbol$cex = .5
mytheme$plot.symbol$col = '#7AC5CD'
mytheme$plot.symbol$alpha = .8

要临时设置主题，请设置晶格的“par.settings”参数绘图功能。例如，这就是latticeExtra将ggplot2设置为主题的方式：

library(latticeExtra) 
xyplot(exp(1:10) ~ 1:10, type = "b", 
       par.settings = ggplot2like())

如何在格子中设置默认的par.settings主题
