CSC 152: The Week beginning Oct. 1

Homework:
- Watch and summarize and/or respond to (in your own words) the following article
  How we'll become cyborgs and extend human potential(Ted Talk by Hugh Herr)
- Read and summarize and/or respond to (in your own words) the following article
  Grace Hopper confab offers optimism amid #MeToo, Supreme Court hearings (article by Erin Carson)
Due: Oct. 8
Monday:

R and RStudio are free downloads. If you want your own copy, you can find youtube videos that instruct one how to download and install the software. (It is not a requirement.)

R Program Read from CSV file uses FluidData.csv (When you submit your .R file you should also submit the CSV file you made for the Heart Rate data.)

Make your own version of the following

(The other formats for saving images are svg and pdf. Use these formats to save a histogram and boxplot of the low temperatures.) Zip up your .R and .CSV as well as your .jpg, .png, .svg and .pdf files and submit them.

Due: Oct. 8
Wednesday:

uses EndangeredSpecies.csv

YversusX.R (This program is just an example. Some people had problems with abline. This program offers a suggestion of what might have gone wrong -- confusing x and y axes. It also offers an alternative to abline called curve which allows one to plot functions in R.)

Due: Oct. 10 (The bargraph and piegraph programs should be submitted along with the files made from them.)
Friday:

I was unhappy with the long paths starting with "C:/..." but I also did not always want to put my data files in the folder RStudio pre-established as the "working directory". If I bring in the rstudioapi library it allows me to figure out where my R program is located and set that as my working directory. That way so long as the R program and the data (csv) file it's reading are together it should work.
```
		#install.packages("rstudioapi")
		library(rstudioapi)
		setwd(dirname(rstudioapi::getActiveDocumentContext()$path))
		getwd()
		biomass=read.csv("MarineReserve.csv")
		
```
1. Write an R program that reads the data file DayOfBirth.csv and makes a bargraph of the data. (While the result you are making is a histogram, do not use R's histogram hist method because the frequencies have already been determined -- we had this same issue of using automatic histograms and making our own in Excel.) Recall that you may want to rename the field names that come with the file. When you have a graph you like, add the line of code before and after to save the result in one of the following formats: jpg, pdf, png or svg.

2. Repeat the above exercise with the data following file Powerball.csv

3. Write an R program that reads the data file MarineReserve.csv. This time use the histogram hist method. When you have a graph you like, add the line of code before and after to save the result in one of the following formats: jpg, pdf, png or svg.
