Yes, I sort of guess at that one and found the answer. I don't quite
really get what this 'with' command is really doing. It seems that I
could have written something like out$Final <- out$Initial+out$Offset.
(Untested.) I guess it's primarily a way of not having to write the

Regarding the Final column the last line should have been

Hi,
No, it's not about cumsum specifically. It's about building up the
list as the events go by.
I managed to create this code but it does depend on a for loop.
Notice how the Final value on each row becomes the Initial value on
the next row. Basically I want to build a data.frame with 5-10
Very interesting. Thanks. Very concise! interesting use of cumsum.
I'll have to see if I can work that into my real code where I need to
take a conditional cumsum. I think it will work.
On my system the Final column doesn't seem quite right but that's OK.
There's enough here for me to study and I
Here `out` is the same as the final value of `MyDF` in your code

Offset=round(100*rnorm(10), 0), Final=0 ))

Because R does not try to evaluate (-8)^(1/3)
The correct mathematical "answer" is really one (or perhaps all
three?) of three complex numbers that are the solutions to x^3+8=0.
Here is one of the others:

I am not entirely clear on what you want to do but
if you simply want a cumulative sum use cumsum:

or to do cumsum using Reduce and + try:

Your data has commas in the numbers causing them to be read in as factors:

First of all, read FAQ 7.31 to understand that 1/3 is not
representable in floating point. Also a^b is actually exp(log(a) * b)
and log(-8) is not valid (NaN).
You expression is not really taking the cube root; it is taking values

Hi Gabor,
Thanks for the pointer to Reduce. It looks quite interesting. I
made an attempt to use it but I'm not clear how I would move the

Row 2. In this output:
