[R] mode of frequency distribution table

[andrija djurovic]

Hi. You can do something like this:
#find the most frequent values of x
> t <- table(x)
> t[t==max(t)]
5
8
#sort table t based on frequencies
> t[order(as.numeric(t),decreasing = TRUE)]
x
  5   6   4  17   1   2  13  30 100 300
  8   5   4   2   1   1   1   1   1   1
#extract any range from sorted table
> t[order(as.numeric(t),decreasing = TRUE)][1:3]
x
5 6 4
8 5 4

I hope this helps.

Andrija
