[R] ? data.entry "read-only" ?

[David Firth]

The function showData() in the relimp package does something like this  
(and has a go at your bonus question), in a Tk widget.  It's far from a  
polished product, but gives some idea of what can be done using the  
tcltk package.  Usage is, for example,

data(trees)
showData(trees)

It will be very slow with very large datasets, but fine for smaller  
ones.

I just discovered, though, that showData() has at least one serious  
bug, arising from changes (quite a while ago now! I should have mended  
this earlier) in the tcltk package.  I'll put a new version of relimp  
on CRAN soon, and in the meantime I have put a fixed version of  
showData() at

software/relimp/showdata.r
--  In case it's of use.
