R中的Punchcard图

有谁能帮我在R中创建punchcard图（不使用ggplot）吗

就像用python制作的一样： 这个怎么样

pctable<-data.frame(expand.grid(c("monday","tuesday","wednesday","thursday","friday","saturday","sunday"),1:22))
colnames(pctable)<-c("weekday","day")
pctable$value=rnorm(nrow(pctable),15,8)
plot(pctable$day,pctable$weekday,cex=pctable$value/(max(pctable$value)/5), col=rgb(0,0,1), pch=19, yaxt="n", xaxt="n")
axis(1, at=1:22, labels=c(1:22)) 
axis(2, at=1:7, labels=c("monday","tuesday","wednesday","thursday","friday","saturday","sunday"), cex.axis=0.7)

pctable黑色边框在原始图形上看起来不错。它可以用
符号（）复制。
<添加代码>sqrt（（pctable$value/max（pctable$value））/pi）

以确保值与符号的表面成比例，而不是与其半径成比例

pctable <- data.frame(expand.grid(weekday=c("Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"),
                              day=1:22), value=abs(rnorm(nrow(pctable), 20, 30)))

par(list(las=1, mar=c(6,6,1,1), mgp=c(4.5,1,0)))

bubble.size <- sqrt((pctable$value / max(pctable$value)) / pi)
symbols(pctable$day, pctable$weekday, circles=bubble.size,
    inches=.2, fg="black", bg="blue", yaxt="n", xaxt="n", xlab="Day", ylab="Weekday")
axis(1, at=1:22, labels=c(1:22)) 
axis(2, at=1:7,labels=rev(c("Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday")), cex.axis=0.7)

pctable我知道你没有要求ggplot2，只是为了向未来的用户展示ggplot2是多么容易（使用特洛伊的数据）：
library（ggplot2）；ggplot（pctable，aes（天，工作日，大小=值））+geom_点（shape=21，fill=“blue”）
