Question

使用theme_classic（）会返回预期格式的图表，但缺少轴线。

使用theme_bw（），之后添加轴线仍然不显示轴线。例如

qplot(input_data$trait1, input_data$trait2) + 
theme_bw() + 
theme(axis.line = element_line(colour = "black", size=10, linetype = 1))

检查theme_bw（）看起来好像大小和线型需要从NULL变为某种东西。

$ axis.line            :List of 4
  ..$ colour  : chr "black"
  ..$ size    : NULL
  ..$ linetype: NULL
  ..$ lineend : NULL

我尝试使用轴线创建一个新主题，但它不被识别为命令：

theme_classic2 = theme_set (theme_classic())
theme_classic2 = theme_update(axis.line = element_line(colour = "black", size=1,
                                                   linetype = 1)

我有一种感觉，我可能不小心改变了一些默认设置。

请帮忙。这相当令人愤怒，更不用说相当尴尬了。
