Hi,
I am new to R plot. I am trying to increase the data point

in the about example 1, 10 would be displayed larger than the other
data points. Could someone give me some ass

Alternatively, you could make use of transparency (on some devices), or use
ggplot2 to map the number of observations to the point size,
d =
read.table(textConnection("
x y
1 10
1 10
2 3
4 5
9 8
"),head=T)
library(ggplot2)
# transparency
qplot(x, y, data=d, al
