Best answer
You can use the table() function to print the frequency of each element present in a vector. In your case: >count <- table(numbers) >count Output: numbers 4 5 23 34 43 54 56 65 67 324 435 453 456 567 657 2 1 2 2 1 1 2 1 2 1 3 1 1 1 1 For a particular element, use the following code: > count[names(count)==56] 56 2
