[R] write.table

[lauramorgana at bluewin.ch]

Sorry, I'm using R 2.8.1 on Microsoft Windows XP professional 2002 Service Pack 2.
The error I get is 
 Error in write.table(x, file, nrow(x), p, rnames, sep, eol, 
> na, dec, as.integer(quote),  : 
    'list' type not implemented in 'EncodeElement'
The problem is that I can' t manage to save the dataframe...
With other dataframe I usually have no problems!!!

Laura,

What do you mean by "It doesn't work"?  Do you get error messages?  Or, do
you just not get what you want?  And if so, what is that you want?
