The usual way of copying 2-dimensional arrays to and from the clipboard is to
separate columns by <Tab> character, and to separate lines by <Newline>
character (CR-LF under DOS/Windows).
Potential problems (at least the three I can see immediately): dimnames, factors
I would suggest that including dimnames should be optional.
I would assume that factors should be copied as.character(...) TO clipboard.
When pasting FROM the clipboard, it would be nice to have an option for leaving
the character vectors as text or transforming them into factors. (I often have
to do a lot of gymnastics to transform factors into character vectors in
dataframes with S+, and I really don't like it).
The NAs could be represented by empty cell, i.e. <Tab><Tab>, for both copy and
In S-PLUS 2000, one can copy and paste data from the data editor, but it seems
that the dimnames don't get copied.
In fact, I think that the clipboard operations should work like read.table and
write.table, except that under R , 'file="clipboard" ' apparently uses an
internal clipboard, and not the standard Windows clipboard.
With S-PLUS 2000, if you say
you can paste the data into Excel.
You can also read data from Excel by
