[R] edit.data() read-only?

[(Ted Harding)]

Sorry, I meant "data.entry()", not "edit.data()" (the latter due
to mental cross-wiring with "edit.data.frame()").

I think that Nello Blaser's suggestion of "View" may be what I
seek (when I can persuade it to find the font it seeks ... )!

With thanks, Barry.
Ted.
