Statistical Analysis with R

The digital world we live in has given companies and people access to staggering amounts of data, and anyone who can make use of that to drive valuable insights stands to benefit. The ability to work with large amounts of data is becoming a standard requirement for countless jobs across multiple industries.

R, probably the most well-known language for data analysis, has been used for years due to its robust statistical functionality, outstanding graphing ability, and extensibility through packages.

This interactive module will get us up to speed with R and assumes no prior knowledge of it. We'll start with the very basics and work our way up to advanced concepts like exception handling. By the time we're done, we'll be able to write detailed, useful code in R.

## Problem Statement
Implement a function `findTopper()` that takes input from three subject files: `math.csv`, `english.csv` and `science.csv`, and find the index of the student that has scored the maximum total marks adding all three of its marks.

### Input
Three files: `math.csv`, `english.csv` and `science.csv`

### Output
Index of the highest scoring student

### Sample Input
`math.csv`
```
Name,   Math
Andrew, 2.5
Mathew, 5.9
Dany,   1.9
Philip, 9.1
```
`english.csv`
```
Name,   English
Andrew, 8.2
Mathew, 2.5
Dany,   7.5
Philip, 9.3
```
`science.csv`
```
Name,   Science
Andrew, 5.2
Mathew, 9.5
Dany,   7.1
Philip, 1.9
```

### Sample Output
```
4
```
