To find the kth most frequent element in an array in R, we can use a combination of loops, sorting, and algorithms. Here is one way to do it:
main.r973 chars31 lines
In this code, we iterate over the elements of the array my_array
and store their frequency in the dictionary freq_dict
. We then sort the dictionary by frequency in descending order using the sort()
function. Finally, we extract the kth most frequent element from the sorted dictionary and print it to the console. Note that if the array does not have k unique elements, we print an error message instead.
