如何将包含多个变量的列转换为单独的变量列

给定一个时间，我有九个不同主题的每个活动值。我想实现这一主题列转化为9个新的变量，例如，我有以下结构：

时间，活动，主题1，主题2，...，主题9

在哪里主题变量包含值的相应条目。

所以在最后我希望有时间的每一个点，8个活动和

Time | ACTIVITY | Subject1 | Subject2 | ... | Subject9 
    -----| ---------|----------|----------|-----|---------- 
    1995 | A  | example | example |  | example 
    1995 | F  | example | example |  | example 
    1995 | K  | example | example |  | example 
    1995 | J  | example | example |  | example

...

我已经尝试过了reshape命令， reshape wide ACTIVITY, i(Value) j(Subject) string但我怀疑reshape isn'在这里输入正确的命令来获得我想要的结果。

屏幕截图的使用非常有限：读者在屏幕截图和问题之间来回切换，无法复制并粘贴到他们的Stata中。请发布一个明确的数据示例。 'dataex'（SSC;使用'ssc inst dataex'安装）将有所帮助。我们不能评论你的'reshape'命令，因为你没有给出代码。请研究http://stackoverflow.com/help/mcve –

感谢您的编辑。这些数据的'reshape'命令是错误的。请参阅下面的答案。 –

在Stata中，列是矩阵的列。你所称的列是变量。

你的屏幕截图显示了以下几个问题：

你Time变量和Value变量是字符串。这看起来不对。这些变量中可能存在某些垃圾。也许标题已被复制到数据中。 list Time if missing(real(Time))是一种会显示非数字值的命令。
您的Subject变量显示尾随空格。如果不一致，可能会导致问题。
您的Subject变量的不同值不能是给定嵌入空格的变量名称的一部分。所以，我们需要一些额外的工作。

此代码生成一个玩具的例子，并展示一些技巧。与你的猜测相反，reshape是首选命令。
