Hello, everyone. I have some problems using the command unapply, let me explain you: First, I create the variables fv and vv. Then, I use the unapply command with fv and vv as argument; the problem is that the command unapply doesn't recognize the content in the variable vv as you can see in the image. Is there a way to make it work the way it should be?(just like in the last line in the image).
I know I could use other commands like subst, however I prefer to use unapply and apply. I hope you can help me, thanks.
