Mini-project description — Rock-paper-scissors-lizard-Spock

	# Rock-paper-scissors-lizard-Spock

	# The key idea of this program is to equate the strings
	# "rock", "paper", "scissors", "lizard", "Spock" to numbers
	# as follows:
	#
	# 0 - rock
	# 1 - Spock
	# 2 - paper
	# 3 - lizard

timmyshen / count.R

Created October 20, 2013 03:57

Write a function named count that takes one argument, a character string indicating the cause of death. The function should then return an integer representing the number of homicides from that cause in the dataset. If no cause of death is specied, then the function should return an error message via the stop function.

	# count.R

	# setwd("~/ComputingForDataAnalysis/Assignment4")

	count <- function(cause = NULL) {
	## Check that "cause" is non-NULL; else throw error
	if (is.null(cause)) {
	stop("Cause has not been specified.")
	}

timmyshen / agecount.R

Created October 20, 2013 03:59

The goal of this part is to write a function called agecount that returns the number of homicide victims of a given age. For most (but not all) records there is an indication of the age of the victim. Your function should take one argument, the age of the victim(s), extract the age of the victim from each record and then return a count of the nu…

	# agecount.R

	agecount <- function(age = NULL) {
	## Check that "age" is non-NULL; else throw error
	if (is.null(age)) {
	stop("Age input cannot be NULL")
	}

	## Read "homicides.txt" data file
	homicides <- readLines("homicides.txt")

	// Homework 1
	// Color to Greyscale Conversion

	//A common way to represent color images is known as RGBA - the color
	//is specified by how much Red, Grean and Blue is in it.
	//The 'A' stands for Alpha and is used for transparency, it will be
	//ignored in this homework.

	//Each channel Red, Blue, Green and Alpha is represented by one byte.
	//Since we are using one byte for each color there are 256 different
