R help - Nov 2006 - a list with row.names = c(NA, 1000)

R users,

I posted a message on "error message for row names". I looked at a
saved
file that has a list structure.
I found that some of list components have row.names = c(NA, 1000). I 
compared what I did with R.2.3.0 with what I did with R.2.4.0.

Previously, with R.2.3.0, row.names = c("1", "2",
"3", ...., "1000"). What
do I need to read the list with row.names attributes have NA ?

TK,

Not to have saved it like that...

Seriously: Do not use dput() for writing out objects, and if you must,
remember to set control="all".

If you have already created such a file and cannot remake it, the fix
should be to edit the row.names component so that row.names = c(NA,
as.integer(1000)).

I guess we could try harder to see if we can convert rownames to
integer, but the advice to avoid dput still stands.
