-0.01*高度中出错：R中的二进制运算符的非数字参数

#我试图在条形图中可视化我的数据（我刚开始使用R，所以我尝试了一些东西）。类似的语法适用于前两个图形，但是，对于这一个，我不知道问题出在哪里

s22 <- list("SUP Bottle"= 517.36, "Bottle Caps"= 10.52, "SUP Cups"= 37.96, "Tin"= 58.4, "SUP Bag"= 792.79, "Food Container"= 71.09, "Cloth"= 20.26, "Polyester bag"= 75.8, "Tetra Pack"= 11.09, "Packaging"= 347.36, "Wood"= 246.68, "Rubber"= 670, "Cardboard"= 470.73, "Iron Rod"= 344.21, "plastic pipe"= 40, "Aluminum"= 64, "lubricant bottle"= 102.17, "shoe"= 470.88)

s22将列表转换为数据帧。然后运行代码

s22谢谢，它在一定程度上起作用了，需要自定义图形。非常感谢。谢谢，它在一定程度上起了作用，需要自定义图表。非常感谢你。
