Explore the basics of the R language, such as variables, operators, loops, and functions, and solve a few challenges.

Become an R Developer

This module will get us up to speed on R programming and assumes no prior knowledge of the language. We’ll start with the basics of R, such as variables, data types, operators, etc., and work our way up to advanced concepts like functions, classes, and exception handling. We’ll also go through some challenges to enhance our hands-on experience. By the time we’re done, we’ll be able to write detailed, useful code in R.

# Problem Statement
Implement a function `calculateLog()` that takes a `testVariable` and prints its `log`. If the **logarithmic value** of the `testVariable` is not possible, print "This operation is not allowed!"

> Use the `cat()` function for printing!

## Input
A `testVariable` containing the data whose **logarithmic value** needs to be found.

## Output
The correct output based on the `testVariable`.

## Sample Input
```
"a"
```
## Sample Output
```
This operation is not allowed!
```
## Test Yourself
Write your code in the given area. If you get stuck, you can look at the solution.

Let's test your understanding of using try catch in R code.
