Custom Functions in R - Histogram

In this assignment, we will build custom functions in R. As an example, the following function called addPercent converts a value into a percentage with one decimal place.

addPercent - function(x){

 percent - round(x*100, digits = 1)

 result - paste(percent, "%", sep = "")

 return(result)

}

Below are a few output results from this function. 

addPercent(.1)

[1] "10%"

addPercent(10)

[1] "1000%"

addPercent(10.1)

[1] "1010%"

addPercent(0.1443)

[1] "14.4%"

1. Please provide a custom R function that inputs a temperature in Fahrenheit Fo and converts to Celsius Co. The relationship is Co = 5(Fo - 32)/9.
2. Please provide a custom R function that computes the sum of squares of two numbers.
3. Please provide a custom R function that takes any univariate dataset and calculates the mean, minimum, maximum, and standard deviation.
4. In statistics, a dataset needs to be transformed in order to meet certain assumptions. Please provide a custom R function that takes any univariate dataset and creates a histogram of the raw dataset and a histogram of the log-transformed dataset. 
5. Please provide a custom R function of your own. Describe what your function does and produce the output.

Include your functions along with at least four different output results from each of the functions 1 through 5.
