why am I using a simple code that doesn´t work?

[RSheila]

I am using a simple code to map a graph from mpg database:

library(ggplot2)
ggplot(data=mpg)
geom_point (mapping=aes(x=displ, y= hwy)
when I type this, there is no error but but graph is plot in blank
Can anyone help me?
thanks

You need to add a "+" between ggplot() and geom_point() (or any other ggplot element) . The code below works:

library(ggplot2)

ggplot(data=mpg) + 
  geom_point (mapping=aes(x=displ, y= hwy))

@gbravo

library(ggplot2)

ggplot(data=mpg) + 
  geom_point (mapping=aes(x=displ, y= hwy))

Thanks a lot! Now it is working. Im starting with R so I really appreciate any help!
