[R] Simple question about symbols()

[murilofm]

The link to the csv file is

http://www.filedropper.com/data_5

I use the "d" variable to create the radius:

radius <- sqrt( inv$d/ pi )

and i tried

symbols(inv$a, inv$b, circles=radius, inches=0.35, fg="white",
   bg="red", xlab="aa", ylab="bb",
   col=c("blue","red")[inv$c+1])

Thanks for the help.
