require(purrr)

list <- list( 
  node = list(a = list(y = 1, t = 1), b = list(y = 1, t = 2)),
  node = list(a = list(y = 1, t = 3), b = list(y = 1, t = 4))) 

如何用purrr选择所有"t"值？

我正在尝试设置刻度尺寸,但是当我指定axis.ticks参数时,刻度在两个轴上都变为水平.例如

data <- data.frame(x =c(1:10), y = c(1:10) )
ggplot(data, aes(x, y)) + 
  geom_point() +
  theme(axis.ticks = element_line(size = 5))

并且角度参数不起作用.

ggplot2版本2.2.0.9000

任何帮助,将不胜感激.
