如何檢索值模式

Question

目標是根據列及其數據檢索模式。

data <- data.frame(test=c("a","b","c","a","a","a","a","c","c","c","c","c","c")) 

是否存在的R內置函數或計算的data$test模式標準的方式？

Answer 1

table(data$test) 

#a b c 
#5 1 7 


table(data$test)==max(table(data$test)) 

# a  b  c 
#FALSE FALSE TRUE 

或

names(table(data$tes)[table(data$test)==max(table(data$test))]) 
#[1] "c"
