![### Sum in Range Script
This script calculates the sum of all integers between two given numbers, inclusive. Below is the detailed transcribed and explained code snippet:
```r
1 input <- readLines('stdin')
2 x <- as.integer(input[1])
3 y <- as.integer(input[2])
4 #define the function
5 rangeSum = function(x, y) {
6 sum = 0
7 for (i in x:y) {
8 sum = sum + i
9 }
10 return (sum)
11 }
```
**Explanation:**
- **Lines 1-3:**
- `input <- readLines('stdin')`: Reads input from the standard input.
- `x <- as.integer(input[1])`: Converts the first input value to an integer and assigns it to variable `x`.
- `y <- as.integer(input[2])`: Converts the second input value to an integer and assigns it to variable `y`.
- **Lines 4-11 (Defining the function):**
- `rangeSum = function(x, y) {`: Defines a function named `rangeSum` that takes two arguments `x` and `y`.
- `sum = 0`: Initializes a variable `sum` to zero which will keep track of the running total.
* Loop and Summation:
- `for (i in x:y) {`: A loop that iterates from `x` to `y`, inclusive.
- `sum = sum + i`: Adds each integer `i` to the `sum` in each iteration.
* Returning the Result:
- `return (sum)`: Returns the computed sum.
