回复 第1楼 的 cloud wei：
请教楼主，刚安装了beanplot包，对于下面范例中的一段，始终不解，盼解疑：
#ToothGrowth是beanplot自带的数据，下面是对该数据根据dose剂量不同进行比较：
beanplot(len ~ reorder(supp, len, mean) * dose, ToothGrowth,
side = "b", col = list("yellow", "orange"), border = c("yellow2",
"darkorange"), main = "Guinea Pigs' Tooth Growth",
xlab = "Vitamin C dose mg", ylab = "tooth length", ylim = c(-1,
40), yaxs = "i")
legend("bottomright", bty="n",c("Ascorbic acid", "Orange juice"),
fill = c("yellow", "orange"))
[s:16]问题： "reorder(supp, len, mean) * dose"这段是什么意思？
