Acacia and Ants Stacked Plots (Graphing)

An experiment in Kenya has been exploring the influence of large herbivores on plants.

If ACACIA_DREPANOLOBIUM_SURVEY.txt is not in your workspace download it. Read it into R using the following command:

acacia <- read_tsv("ACACIA_DREPANOLOBIUM_SURVEY.txt", na = c("dead"))

1. Make a non-stacked histogram of the height of acacia (using the HEIGHT column) colored by the TREATMENT. Set the transparency (using alpha) to 0.5 so that you can see all of the bars. Label the x-axis “Height (m)” and the y-axis “Count of Acacia”. Set the binwidth to 0.5.
2. Make a non-stacked histogram of the circumference of acacia (using the CIRC column) colored by the ANT column. Set the transparency (using alpha) to 0.5 so that you can see all of the bars. Label the x-axis “Circumference (cm)” and the y-axis “Count of Acacia”. Set the binwidth to 5.
