Answer 1

ggplot2 - Bar Plot: (Use dataset_student_survey_data.csv)

• x=Smoke

• fill=Exer

• position=dodge

• facet=Sex

• x-label=Smoker

• y-label=Counts

• title=The Exercise habits of Male and Female students that smoke

Answer 2

ggplot2 – Histogram: (Use dataset_us_car_price_data.csv)

• x=Price

• fill=Type

• facet=Type

• x-label=Price

• y-label=Freq

• title=Car Price Distribution based on Car Type

R studio could not produce graph for this because Price is a discrete variable

whereas it needs to be a continuous variable. Following is the syntax used to

produce the chart and also the error from R studio.

ggplot(dpc, aes(x=Price, fill=Type)) + theme_bw() + facet_wrap(~Type) +

geom_histogram() + labs(x="Price" ,y="Freq" ,title="Car Price Distribution based on

Car Type")

Error: StatBin requires a continuous x variable: the x variable is discrete. Perhaps

you want stat="count"?

Answer 3

ggplot2 - Box Plot: (Use dataset_production_of_rice_in_indonesia.csv)

• x=varieties

• y=price

• fill=bimas

• facet=status

• x-label=Rice Varieties

• x-label=Price

• title=Indonesia Rice Prices based on Varieties, Land Status, and Bimas Program
