How to calculate the total sum of an array in R language?

You can calculate the sum of an array in R using the sum() function. Here is an example code for calculating the sum of an array:

# 创建一个数组
arr <- c(1, 2, 3, 4, 5)

# 计算数组总和
total <- sum(arr)

# 打印结果
print(total)

Running the code above will output the sum of the array arr. Alternatively, you can directly pass the array to the sum() function instead of first storing it in a variable.
