Rstudio图，如何在图例上拟合图例和轴标签

Question

嗨，我正在R中从事一项新工作，并且正在创建一个显示样品污染水平的箱形图。我的图形看起来像我想要的样子，但是我无法使图例移动到侧面而不会消失并且x轴标签从底部掉下来。

我的代码如下：

#adds padding to the inner margin of the graph, allows legend and labels to fit
par(mar=c(10,5,3,10)) 

stackedGraphGOOD = barplot(as.matrix(goodKrakenData), 
                              col = c("DODGERBLUE", "GREEN3", "RED"), 
                              ylab = "Percent", border = NA, axis.lty = 1, cex.axis = 1,  
                              main = "Kraken Quality Percentages", 
                              legend.text = c("Unclassified", "Family", "Other"), 
                              args.legend = list(x = 14, bty='y'), las = 2)
         #allows me to adjust the placement of the x-axis label
         title(xlab = "Animal ID", line = 9)

并且我得到一个看起来像这样的图：

我需要调整图表的内部和外部页边距以使其正确显示

taxonomy ID1 ID2 ID3
unclassified 19 5 10
Other 0.0003 0.0006 0.08
primaryFamily 80.9997 94.9994 89.92
