ggplot2 is a flexible and useful tool for creating plots in R.

The data set and coordinate system can be defined using the ggplot function.

Additional layers, including geoms, are added using the + operator.

Histograms and density plots are useful tools to visualise the distribution a a continuous variable.

Scatterplots can be useful in understanding the relationship between two continuous variables.

Bar charts are useful for visualising the frequency of categorical variables.

Box plots show the distribution of a continuous variable across different groups.

Individual data points should be included in a plot whenever possible.

ggplot2 allows plots to be customised in many ways.

The appearance of plot elements can be adjusted individually or via themes.
