Question

我想结合ggplot并像这样操作：

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")
)

（操作函数将使用picker更改x输入）

但我得到Error: unexpected ')' in ")"

编辑1：修复了语法错误（请参阅：({ ... )},）

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

现在我得到了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

Answer 1

由于选择器返回"carat"而不是carat，因此您应该使用aes_string，而不是aes。

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

将ggplot（）与manipulate（）选择器集成
