如何检索值模式 [重复]

Question

目标是根据列及其数据检索模式。

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

是否有R内置函数或标准方法来计算data$test的众数？

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"
