我有像1-10,10-20,20-30,30-40这样的小组。我有像“1,23,24,11,33,22,5,6,7,8,3,2”这样的数据 我怎样才能知道每组中有多少
答案 0 :(得分:7)
您也可以使用hist函数:
y <- c(1,23,24,11,33,22,5,6,7,8,3,2)
h <- hist(y, seq(0, 40, 10), plot=0) # plot=0 avoids plotting the histogram
# Refer to h$counts to get the counts in each bin

R> table(cut(c(1,23,24,11,33,22,5,6,7,8,3,2),
breaks=seq(0, 40, by=10), right=FALSE))
[0,10) [10,20) [20,30) [30,40)
