Observation’s Values in the Spreadsheet Viewer

Can we edit an observation’s values in the spreadsheet viewer?

Recall that we used the View(pwt7) to open and eyeball the pwt7 data frame in a spreadsheet interface. In addition to View(pwt7), one can also use fix(pwt7) to view data. Yet while both can be used to view data, they are extremely different functions. View() just allows one to view data, but fix() allows one to not only view but also to edit and change values of a dataset within the spreadsheet viewer.
