r语言go分析气泡图 r语言分析geo数据( 二 )

IT技术IDA


原来这个参数默认值是30 ， 当标签的长度大于30个字符就会被折叠，用多行来展示 。既然问题找到了，我们就来调节一下这个参数 ， 把他设置成100，让我们的标签可以一行展示 。
是不是还是原来的配方，还是熟悉的味道
同样的柱形图，我们也能让他恢复原来的容貌 。
关于如何使用R做GO和KEGG富集分析 ， 可参考下文

《R语言实战》自学笔记66-气泡图数据准备
气泡图（bubble plot）：在二维散点图的基础上，用点的大小来代表第三个变量的值 。
symbols()函数来创建气泡图 。该函数可以在指定的(x, y)坐标上绘制圆圈图、方形图、星形图、温度计图和箱线图 。
symbols(x, y, circle=radius)
其中x、y和radius是需要设定的向量，分别表示x、y坐标和圆圈半径 。
你可能想用面积而不是半径来表示第三个变量，那么按照圆圈半径的公式（r = /πA ）变换即可:
symbols(x, y, circle=sqrt(z/pi))
一般来说，统计人员使用R时都倾向于避免用气泡图，原因和避免使用饼图一样：相比对长度的判断，人们对体积/面积的判断通常更困难 。
