在 R 中使用来自 latticeExtra 的 doubleYScale 时如何更改 Y 轴刻度的字体大小

Question

我想在使用 doubleYScale 时更改 Y 轴刻度的字体大小（不是标签，而是刻度旁边的数字）。我已经设法更改了 X 轴的字体大小，包括 X 轴和 Y 轴标签，但是我在为 Y 轴字体大小而苦苦挣扎。

foo <- list(x = 1:100, y = cumsum(rnorm(100)))
obj1 <- xyplot(y ~ x, foo, type = "l", scales = list(y = list(cex=2)))
obj2 <- xyplot(y ^ 2 ~ x, foo, type = "l", scales = list(y = list(cex = 2)))

doubleYScale(obj1, obj2, add.axis = TRUE)

这里cex对y轴刻度的字体大小没有影响。我应该怎么做？

Answer 1

在您的情况下，也许最简单的方法是：

library(lattice)
library(latticeExtra)
trellis.par.set(axis.text=list(cex=2))
doubleYScale(obj1, obj2, add.axis = TRUE)

如果您不想更改默认设置，请尝试以下操作：

update(doubleYScale(obj1, obj2, add.axis = TRUE),
par.settings =list(axis.text=list(cex=2)))
