The smooth layer is different to the point layer because it doesn’t display the raw data, but instead displays a statistical transformation of the data.Specifically, the smooth layerfitsa smooth line through the middle of the data.This requires an additional step in the process described above:...
ggplot2是一个用于数据可视化的R语言包,它提供了丰富的图形语法和灵活的绘图功能。在ggplot2中,geom_point和geom_line是两个常用的几何对象,用于绘制散点图和折线图。 为了为geom_point和geom_line创建不同的配色方案,可以使用ggplot2提供的颜色函数和调色板。下面是一个完善且全面的答案: ...
因变量可以为数值型变量或者分类变量。可供选的函数有： geom_line(), geom_step(), geom_path()...
p <- ggplot(mtcars, aes(wt, mpg)) p + geom_point() 2. geom_line() geom_line()函数将所有的数据点按照x轴上变量的顺序连接它们。 用法: geom_line( mapping = NULL, data = NULL, stat = "identity", position = "identity", na.rm = FALSE, orientation = NA, show.legend = NA, inheri...
