Canging the type of point points sizein plots..

try this

x1 <- rnorm(10); y1 <- rnorm(10)
x2 <- rnorm(10); y2 <- rnorm(10)
x3 <- rnorm(10); y3 <- rnorm(10)
#################
plot(range(x1, x2, x3), range(y1, y2, y3), type = "n")
points(x1, y1, pch = 1, cex = 1, col = 1)
points(x2, y2, pch = 2, cex = 2, col = 2)
points(x3, y3, pch = 3, cex = 3, col = 3)


I hope it helps.

Best,
Dimitris
