另外，需要准备分组文件 . 集団構造解析ソフトAdmixtureの使い方 - Fujinitakaの日記 Observed ( H o ) and expected ( H e ) heterozygosities, as well as the inbreeding coefficient F hat2 , were calculated by using the PLINK v.1.7 software (Purcell et al., 2007 ) and the data set of 1001 SNPs. Here's one approach for plotting a set of faceted stacked barplots showing the output from popular software and methods (e.g. ggplot2: Elegant Graphics for Data Analysis by H. WICKHAM 具体而言， ADMIXTURE 使用 块松弛（ block relaxation） 方法来交替更新等位基因 . This type of plot is called a grouped bar plot . 在拿到群体结构软件 （STRUCTURE，fastStructure，admixture）分析的 Q 数据之后下一步就是怎么把数据可视化做出堆叠图。 方法一： 1barplot(t(as.matrix(data)),col=rainbow(2),axes=FALSE,ylab="K=2",font=2,cex.lab=1.4) # col=rainbow(2)中的数字为计算时的K值 方法二： 12 Plots the distribution of genomic frequencies within a region as a joyplot, where the change over time in the distribution is visualized: plot_start_end - output of simulate_admixture - selection of ancestors to plot; Plots both the initial and final frequency of each ancestor along the genome The ggplot2 package allows customizing the charts with themes. More advanced figures (ggplot2) R users favor using ggplot2 that adds functionality to the basic plots seen above. If you haven't used ggplot2 before, it may at first be a bit odd because it deviates from normal plotting approaches where you just shove a bunch of arguments into a single .

If they differ considerably, then the admixed population may be . 2) Example 1: Drawing Grouped Barchart Using Base R. 3) Example 2: Drawing Grouped Barchart Using ggplot2 Package.
