Question

In R, mean() and median() are standard functions which do what you\'d expect. mode() tells you the internal storage mode of the objec

Answer 1

Could try the following function:

1. transform numeric values into factor
2. use summary() to gain the frequency table
3. return mode the index whose frequency is the largest
4. transform factor back to numeric even there are more than 1 mode, this function works well!

mode <- function(x){
  y <- as.factor(x)
  freq <- summary(y)
  mode <- names(freq)[freq[names(freq)] == max(freq)]
  as.numeric(mode)
}
