Until now, we have changed the colors in a ggplot2 line and point graph. This example illustrates how to modify the colors of a boxplot graphic. For this, we can use the fill argument within the aesthetics of the ggplot function: ggplot(data,# Change colors of boxplotsaes(y=y, fill=...

比如,想对数据框进行分组,分别对每组数据做操作,整体来想这是不容易想透的复杂事情,实际上只需做 group_by() 分组,然后把你要对一组数据做的操作实现;再比如,across()同时操作多列,实际上只需把对一列要做的操作实现。这就是数据分解的操作思维,这些函数会帮你分解 + 分别操作 + 合并结果,你只需要关心分别...
