Add and subtract from single column

[Swincine]

Hello,

I am trying to perform addition and subtraction on same column
So I got the column with name total and it has values
1
2
3
4
5

I need to get a<- 1+2+3 = 6
B<- 4+5 =9
C = b-a = 3

How can I write code for this ?

Please help me

Thank you

I would love to help you, but I don't understand what you are asking for help with it all.

Hi,

I agree with @nirgrahamuk. In order for us to help you with your question, please provide us a minimal reproducible example where you provide a minimal (dummy) dataset and code that can recreate the issue. Once we have that, we can go from there. For help on creating a Reprex, see this guide:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Good luck!

What the guys said above holds, but you can accomplish what you want with the following code.

data <- data.frame(Total = seq(1,5,1))

a <- sum(data[1:3,])
b <- sum(data[4:5,])
c <- b - a
