我正在尝试检索数据框中存在的特定列中重复次数最多的值,这是下面的示例数据和代码。

data("Forbes2000", package = "HSAUR")
head(Forbes2000)


  rank                name        country             category  sales profits  assets marketvalue

根据我的样本数据,我需要返回最重复的类别是保险。

subset(subset(Forbes2000,country=="Bermuda")

最佳答案

tail(names(sort(table(Forbes2000$category))), 1)
