I tried to refer to Counting the number of elements with the values of x in a vector
Initially I used count(). It was working before but now its not.
Why is this giving an error?
countact <- as.data.frame(table(Data$number))
countact$Probability <- countact$freq/sum(countact$freq)
Error in
$<-.data.frame(*tmp*, "Probability", value = numeric(0)) : replacement has 0 rows, data has 4
Looks to me like a simple letter-case problem: you need to use Freq rather than freq:
numbers <- c(4,23,4,23,5,43,54,56,657,67,67,435,453,435,324,34,456,56,567,65,34,435);
countact <- as.data.frame(table(numbers));
countact$Probability <- countact$freq/sum(countact$freq);
## Error in `$<-.data.frame`(`*tmp*`, "Probability", value = numeric(0)) :
## replacement has 0 rows, data has 15
countact$Probability <- countact$Freq/sum(countact$Freq);
countact;
## numbers Freq Probability
