rep(df1[,1],df1[,2]*100)
count(as.character(rep(df1[,1],df1[,2]*100)))
#  x freq

Dear R forum

I have a vector say as given below

df = c("F", "C", "F", "B", "D", "A", "D", "D", "A", "F", "D", "F", "B",    "C")

I need to find 

(1) how many times each element occurs? e.g. in above vector F occurs 4 times, C occurs 2 times etc.

(2) Depending on the number of occurrences, I need to repeat the element 100 times of the occurrences e.g. I need to repeat F 6 * 100 = 600 times, C 2*100 = 200 times.

I can manage the second part i.e. repeating but I am not able to count the number of times the element is appearing in a given vector.

Kindly guide 
 
Katherine
