What is the expression to count the rows/ observations?

  1. This is how I entered data:
Module[{path, nb}, 
 path = FileNameJoin[{NotebookDirectory[], "dataintro.nb"}];
 nb = NotebookOpen[path, CellContext -> "Global`", Visible -> False];
 NotebookEvaluate[nb, InsertResults -> False];
  1. My data looks like table format with Variables: Feet and Price

Thank you for your help!

  • $\begingroup$ Welcome to MSE. Your question is not very clear. What do you mean by table format with Variables: Feet and Price? Can you provide an example? $\endgroup$ – Rohit Namjoshi Sep 24 '19 at 14:57
