In this post you’ll learn how to draw a barplot (or barchart, bargraph) in R programming.The page consists of eight examples for the creation of barplots. More precisely, the article will consist of this infor
在R语言的自带base作图系统中,有一个内置的绘制饼图的函数,叫做pie()函数 它的参数非常简单,需要给出第一个参数就是:数值,也就是我们这个数据中的Value一列 第二个参数就是:数值的标签,也就是我们数据当中的Group一列 #read in data data = read.table("pie_plot.txt", sep="\t", header=T) data #...
barplot(data$value ~ data$group)# Default barchart in Base R As shown in Figure 1, we have managed to create a bargraph by executing the previous code. However, since our graphic contains too many bars, not all axis labels are shown. Let’s change that! Example 1: Show All Barchart...
mtext("The detected number of ARGs in all samples", 添加图例 首先要新建一个绘图区,并且建立一个空的图用来辅助图例的添加。 par(xpd=TRUE) 之后要分两次添加图例,第一次添加条形图的图例,第二次添加“点+垂线”图的图例。 legend(0,1.12,legend = rownames(args.mges.number[1:8,]), 在条形图的图...
with heights given by the values in the vector. If height is a matrix and beside is FALSE then each bar of the plot corresponds to a column of height, with the values in the column giving the heights of stacked sub-bars making up the bar. ...
