按列转换data.frame

如何解决按列转换data.frame

我有一个像这样的data.frame：

// A class which uses injected dependencies
class NeedSomeDependeciesToBeInjected
{
    public NeedSomeDependeciesToBeInjected (
        IThisIsReallyImportant important,IThisIsUsefulButNotImportant useful) {}
}

// A complex dependency,which requires other injected dependency
// (So,yes,recursion...)
class ThisIsReallyImportant : IThisIsReallyImportant
{
    public ThisIsReallyImportant (
        IThisIsrequiredToBecomeImportant required) {}
}

// A dependency,which does not require other injected dependency,// but is required for another dependency
class ThisIsrequiredToBecomeImportant : IThisIsrequiredToBecomeImportant 
{
    public ThisIsrequiredToBecomeImportant () {}
}

// A simple dependency,// and is not required for others
class ThisIsUsefulButNotImportant : IThisIsUsefulButNotImportant
{
    public ThisIsUsefulButNotImportant () {}
}

class Program
{
    private readonly WeaponOfChoiceInIoC container;

    public void ConfigureDependencies()
    {
        container = new WeaponOfChoiceInIoC();

        container.Register(IThisIsrequiredToBecomeImportant,ThisIsrequiredToBecomeImportant);
        container.Register(IThisIsReallyImportant,ThisIsReallyImportant );
        container.Register(IThisIsUsefulButNotImportant,ThisIsUsefulButNotImportant );
    }

    public void MethodToPlayWithDependencies()
    {
        var toy = container.GetInstance(NeedSomeDependeciesToBeInjected);
    }
}

我尝试了mutate并进行了转置，但是没有得到正确的结果。

谢谢
