ggplot2 package| How to create bar chart?

A bar graph is a frequently used type of display that compares counts, frequencies, totals or other summary measures for a series of categories, e.g. sales in different market sectors or in quarters in a financial year. The bar graph can be laid out with the categories either on the vertical or horizontal axis of the display – depending on whether we consider making a vertical or horizontal comparison is easier for interpreting the graph.

In ggplot2, the bar graph is created using geom_bar ( ) object. ggplot ( ) function uses statistical transformations (stat="count") of the data frame to create frequency bar graph i.e. counting number of occurrences the categorical variable in a data set.
The statistical transformation (stat="identity") is used to plot the raw values of the categorical variable.
