r语言 绘制直方图

In this tutorial, we’ll go over the steps to plot a histogram in R. A histogram is a graphical representation of the values along with its range. It is similar to a bar plot and each bar present in a histogram will represent the range and height of the specified value.

在本教程中，我们将介绍在R中绘制直方图的步骤。 直方图是值及其范围的图形表示。 它类似于条形图，直方图中的每个条形都将表示指定值的范围和高度。

R offers standard function hist() to plot the histogram in Rstudio. It also offers function geom_density() to plot histogram using ggplot2.

R提供标准函数hist（）来绘制Rstudio中的直方图。 它还提供了函数geom_density（）来使用ggplot2绘制直方图。

Based on the distribution of the data, a histogram exhibits many different shapes. In this section, we will try to understand the different types of histogram shapes and their meaning.

根据数据的分布，直方图显示许多不同的形状。 在本节中，我们将尝试了解直方图形状的不同类型及其含义。
