This homework is due on Feb. 1, 2024 at 11:00pm. Please +submit as a pdf file on Canvas.
+Problem 1: (6 pts) For this Problem you will be
+working with the iris dataset built into R. This data set
+contains measurements of flowers (sepal length, sepal width, petal
+length, petal width) for three different Iris species (I.
+setosa, I. versicolor, I. virginica).
head(iris)## Sepal.Length Sepal.Width Petal.Length Petal.Width Species
+## 1 5.1 3.5 1.4 0.2 setosa
+## 2 4.9 3.0 1.4 0.2 setosa
+## 3 4.7 3.2 1.3 0.2 setosa
+## 4 4.6 3.1 1.5 0.2 setosa
+## 5 5.0 3.6 1.4 0.2 setosa
+## 6 5.4 3.9 1.7 0.4 setosaUse ggplot to make a histogram of the Sepal.Length
+column. Manually choose appropriate values for binwidth and
+center. Explain your choice of values in 2-3 sentences.

+Problem 2: (6 pts) For this problem you will work
+with the dataset txhouse that has been derived from the
+txhousing dataset provided by ggplot2. See
+here for details of the original dataset: https://ggplot2.tidyverse.org/reference/txhousing.html.
+txhouse contains three columns: city (listing
+four Texas cities), year (containing four years between
+2000 and 2015) and total_sales indicating the total number
+of sales for the specified year and city.

+## 13 San Antonio 2000 15590
+## 14 San Antonio 2005 24034
+## 15 San Antonio 2010 18449
+## 16 San Antonio 2015 16455Use ggplot to make a bar plot of the total housing sales (column
+total_sales) for each year, color the bar
+borders “gray34”, and fill the bars by city.
# Your code goes here.Problem 3: (8 pts) Modify the plot from Problem 2 by
+placing city bars side-by-side, rather than stacked. See
+Slide 35 from the lecture on visualizing amounts. Next, reorder the bars
+for each year by total_sales in descending
+order. See Slide 25 from the lecture on visualizing amounts.
