This post explains how to build grouped, stacked and percent stacked barplot with R and ggplot2. It provides a reproducible example with code for each type.
偶然间找到了一份教程利用ggplot2绘制环状柱形图,个人感觉非常适合用来展示叶绿体基因组蛋白编码基因的dn/ds值,因为不仅能够通过柱状图的高低来比较dn/ds值的大小,还能够通过环状展示蛋白编码基因在叶绿体基因组上所处的位置 A circular barplot is a barplot where bars are displayed along a circle instead of a li...

#载入包 library(ggplot2) #作图参数设置,data对应上面的数据集名字;aes对应x,y轴的数据标签,注意大小写,与数据集保持一致;geom_bar表示制作柱形图 p<-ggplot(data=df, aes(x=group, y=ORR)) + geom_bar(stat="identity") #展示图形 p 3对作图参数进行优化,横纵坐标置换、改变柱子宽度、填充颜色 3.1横...
GGPlot2 Essentials for Great Data Visualization in R Key R functions Key function:geom_col()for creating bar plots. The heights of the bars represent values in the data. Key arguments to customize the plot: color,fill: bar border and fill color ...
then come thes aesthetics, set in theaes()function: set the categoric variable for the X axis, use the numeric for the Y axis finally callgeom_bar(). You have to specifystat="identity"for this kind of dataset. # Load ggplot2library(ggplot2)# Create datadata<-data.frame(name=c("A"...

Figure 6: Grouped Barchart with Legend in R.Compare Figure 5 and Figure 6. Both graphics contain the same values, once in a stacked barchart and once in a grouped barchart.Example 7: Barplot in ggplot2 PackageSo far, we have created all barplots with the base installation of the R ...
ggplot2.barplot is a function, to plot easily bar graphs using R software and ggplot2 plotting methods. This function is from easyGgplot2 package. An R script is available in the next section to install the package. The aim of this tutorial is to show you step by step, how to plot an...
