A histogram is a type of bar chart which shows the frequency of the number of values which are compared with a set of values ranges. The histogram is used for the distribution, whereas a bar chart is used for comparing different entities. In the histogram, each bar represents the height of the number of values present in the given range.
For creating a histogram, R provides hist() function, which takes a vector as an input and uses more parameters to add more functionality. There is the following syntax of hist() function:
Let?s see an example in which we create a simple histogram with the help of required parameters like v, main, col, etc.
Let?s see some more examples in which we have used different parameters of hist() function to add more functionality or to create a more attractive chart.
Example: Use of xlim & ylim parameter
Example: Finding return value of hist()
Example: Using histogram return values for labels using text()
Example: Histogram using non-uniform width
