Use R-Studio Programing to finish this:

1. Create a scatterplot for age (y variable) and fl (x variable) with the following specifications:

• Limit of x axis is (0,500)

• Limit of y axis is (0,15)

• Title of graph is Plot 1: Harrison Lake Trout

• Y axis label is Age (yrs)

• X axis label is Fork Length (mm)

• Use a small filled circle for the plotted data points

10. Plot an Age histogram with the following specifications Y axis label is Frequency X axis label is Age (yrs) Title of the histogram is Plot 2: Harrison Fish Age Distribution

    X and Y axis limits is 0, 15 The color of the frequency plots is cadetblue The color of the Title is cadetblue

11. Create an overdense plot using the same specifications as the previous scatterplot. But,

    • Title the plot Plot 3: Harrison Density Shaded by Era

    • Y axis label is Age (yrs)

    • Y axis limits are 0 to 15

    • X axis label is Fork Length (mm)

    • X axis limits are 0 to 500

    • include two levels of shading for the green data points.

    • Plot solid circles as data points

12. Create a new object called tmp that includes the first 3 and last 3 records of the BullTroutRML2 data set.

13. Display the era column (variable) in the new tmp object

14. Create a pchs vector with the argument values for + and x.

15. Create a cols vector with the two elements red and gray60

16. Convert the tmp era values to numeric values.

17. Initialize the cols vector with the tmp era values

18. Create a plot of Age (yrs) (y variable) versus Fork Length (mm) (x variable) with the

    following specifications:

    • Title of graph is Plot 4: Symbol & Color by Era

    • Limit of x axis is (0,500)

    • Limit of y axis is (0,15)

    • X axis label is Age (yrs)

    • Y axis label is Fork Length (mm)

    • Set pch equal to pchs era values

    • Set col equal to cols era values

19. Plot a regression line overlay on Plot 4 and title the new graph Plot 5: Regression Overlay.

20. Place a legend of on Plot 5 and call the new graph Plot 6: :Legend Overlay
