r語言怎麼把list變成table

table()

引數型別one or more objects which can be interpreted as factors (including character strings)， or a list (or data frame) whose components can be so interpreted. (For as.table， arguments passed to specific methods for as.data.frame， unused.)

我們一般使用將引數轉化為用unlist（）列表轉化為向量型別

返回值為table型別，一種類似於字典的型別
