Hi there, 

I need to do the same thing as cumsum but with the variance and skewness. I
have tried to do a loop for like this: 
       var.value <- vector(mode = "numeric", length = length(daily))
        for (i in (1:length(daily))) { 
           var.value[i] <- var(daily[1:i])

But because my dataset is so huge, I run out of memory.....

Any ideas?!?!

Much appreciate it!
