I need to evaluate the result returned from an external package, which contains
Defer in it, but do this in a script without user interaction.
I am not able to figure how to do this, without actually using the mouse and hitting Shift + Return in the notebook itself. But I need to do this in a program (script) that runs outside the notebook environment.
Here is an example:
r = Defer[Integrate][Cos[x], x]
out cell there has the Defer in it. I want to now evaluate
r. The only way is by moving the mouse to the
Out cell and hit Enter, which now changes the
Out cell to an
In cell and evaluate what was there resulting in:
How do I do the above in a script? I tried
Evaluate[ReleaseHold[r]] and all sorts of things. But I can't get rid of the
Defer. (There is no
RemoveDefer function). The only way is to do evaluate in place which is what the pointing on the cell and hitting Enter does.
How do I remove
Defer from a returned expression and evaluate the result in non-interactive script (i.e. programmatically)?
I am using version 10.1 on Windows 7.
