Integrating ggplot() with manipulate() pickers

I want to combine ggplot and manipulate like this:

library(ggplot2);library(manipulate)

manipulate(
  ggplot(diamonds, aes(x = type, y = price)) +
    geom_point(alpha = 1/10) +
    geom_smooth(method = lm)
  type = picker("carat","depth","table")
)

(where the manipulate function will change the x inputs with picker)

But I am getting an Error: unexpected ')' in ")"

EDIT 1: fixed the syntax error (see: ({ ... )}, )

manipulate({
  ggplot(diamonds, aes(x = type, y = price)) +
    geom_point(alpha = 1/10) +
    geom_smooth(method = lm)},
  type = picker("carat","depth","table")
)

Now I'm getting Don't know how to automatically pick scale for object of type manipulator.picker. Defaulting to continuous Error: Aesthetics must either be length one, or the same length as the dataProblems:type

Since the picker returns "carat" instead of carat, you should be using aes_string, rather than aes.

manipulate(
  ggplot(diamonds, aes_string(x = type, y = "price")) +
    geom_point(alpha = 1/10) +
    geom_smooth(method = lm),
  type = picker("carat","depth","table")
)
