Change shape and color of geom points in ggplot2

Here is the issue, the following code is changing the color of the data points but not the shape. What is wrong?

g <- ggplot(mydata, aes(var1, var2)
g <- g + geom_point(aes(shape=var3, color=var3), shape=1)
g <- g + facet_grid(.~var4)
g <- g + theme(legend.position="bottom") + guides(colour = guide_legend(ncol = 1))

Your code is almost correct. Why do you have two shapes?
Replace 

geom_point(aes(shape=var3, color=var3), shape=1)

With

geom_point(aes(shape=var3, color=var3)

And this is how I would write it:

library(ggplot2)
ggplot(mydata, aes(var1, var2) +
    geom_point(aes(shape = var3, color = var3)) +
    facet_grid(. ~ var4) +
    theme(legend.position = "bottom") + 
    guides(colour = guide_legend(ncol = 1))
