How to get an average of words from a list?

How do I calculate the average number of words in a list using for loop in ? I have a list called mylist which contains 25 vectors with character quotes on each vector.

Here is my code so far:

count <- 0
for (i in mylist[1:25]){
count <- count + i
mean(count)
}

But I get this error :

Error in count + i : non-numeric argument to binary operator

Any help will be greatly appreciated!

We can use lengths to get the length of each vector in the list and then wrap with mean

mean(lengths(mylist))

If we need a loop, then create a vector to store the length

v1 <- numeric(length(mylist))
for(i in seq_along(mylist)) v1[i] <- length(mylist[[i]])
mean(v1)
