Histogram
A histogram is a graphical representation of the distribution of data in a format similar to a bar plot. The bars can be plotted either vertically or horizontally. A simple histogram chart can be created in R with the hist function. In the example below, data from the sample "trees" dataset is used to plot a histogram of tree height.
hist(NumericVector) Example:
> hist(trees$Height) The resulting histogram is very simple. However, users can define arguments to fully customize the appearance of the plot. Each argument is entered within the hist function and separated by a comma. When using the hist function it's often easiest to start with a standard template that lists the most common arguments with a NULL or DEFAULT value (example below). The user can then define whatever arguments they choose to customize the plot.
hist(NumericVector, IMPORTANT NOTES:
The format of the above string includes extra returns after each argument. R does not recognize extra returns in a string, the extra returns are included to make visual identification of each argument quicker and easier. Common Histogram Arguments
Definitions and examples for a few of the more common arguments are provided in the table below. View the subpages under Data Visualization > Histogram to learn more about the use of these arguments in histograms.
