The cumulative sum can be defined as the sum of a set of numbers as the sum value grows with the sequence of numbers.
cumsum() function in R Language is used to calculate the cumulative sum of the vector passed as argument.
Syntax: cumsum(x)
Parameters:
x: Numeric Object
Example 1:
Python3
# R program to illustrate # the use of cumsum() Function # Calling cumsum() Function cumsum( 1 : 4 )
cumsum( - 1 : - 6 )
|
Output:
[1] 1 3 6 10 [1] -1 -3 -6 -10 -15 -21
Example 2:
Python3
# R program to illustrate # the use of cumsum() Function # Creating Vectors x1 < - c( 2 , 4 , 5 , 7 )
x2 < - c( 2.4 , 5.6 , 3.4 )
# Calling cumsum() Function cumsum(x1) cumsum(x2) |
Output:
[1] 2 6 11 18 [1] 2.4 8.0 11.4
