如何规范化R中的圆周大小

I have a data set as follows and am creating a bubbleplot using symbols, with the Z column used as bubble size:

我有一个数据集如下，我正在使用符号创建一个气泡图，Z列用作气泡大小：

 X       Y      Z       TITLE
151.2  31.5    51023     xyz
160.2  51.8    4912      xyz
191.7  2.1     874201    abc

radius <- sqrt(data$z/pi)
symbols(data$x,data$y,circles=radius,inches=0.35,
cex.axis=1.5,cex.lab=1.5,xlab="xlab", ylab="ylab")

I then would like to have a second bubbleplot with any Title of "abc" removed. However, when I do this, the bubbles then resize themselves in comparison to the original plot. How can I normalize bubble size between plots?

然后，我想要第二个气泡图，删除任何“abc”标题。但是，当我这样做时，与原始图相比，气泡会自行调整大小。如何在图之间标准化气泡大小？

Try something like

尝试类似的东西

data$radius <- sqrt(data$Z/pi)/50
with(data[data$TITLE != "abc",],
     symbols(x = X, y = Y, circles = radius,
             inches = FALSE, asp = 1,
             xlim = c(140, 240), ylim = c(-10, 60)))

and

和

with(data,
     symbols(x = X, y = Y, circles = radius,
             inches = FALSE, asp = 1,
             xlim = c(140, 240), ylim = c(-10, 60)))

If you specify inches = 0.35, the circles are scaled to make largest circle dimension 0.35 inches. Read more at ?symbols

如果指定inches = 0.35，则缩放圆圈以使最大圆尺寸为0.35英寸。阅读更多？符号
