Sorry, that I didn't wrote the sum function in latex. I tried $$ but that didn't work...
I am a beginner in R and I want to sum up:
Sum from i=0 to n by 1.054^i
I reserached the sum()
function in R. However, it seems to me that is only can just add elements and not include an index or something.
So my question is: Can I solve that with a simple sum function or do I have to use a for loop for example?
I really appreciate your answer!
UPDATE
Here is a link to my sum(sorry that I cannot post it, but I need more reputation :(link )

In R most operations are vectorized, it requires changing the mindset a bit from other languages and for this question the answer is rather than looping, you simply do the entire operation on your sequence of numbers "at once":
sum(1.054^(0:n))
