good morning
I'm using R 2.2.1 on windows (2000/NT/XP) and trying to upgrade to 2.3.1
I am finding the curious problem of date/time data (both if stocked as date and
as POSIX) that gets converted into character format whenever touched: it seems
that date/time data just does not want to remain that way.
For example, a data.frame containing dates or POSIXct as row.names that is
returned as result from a function arrives to the calling function with
characters as row.names:
pippo<-function(...) {
result<-data.frame( ... )
attributes(result)$row.names<- ... (some dates or POSIX)
#mode(attributes(xx)$row.names) is now numeric, = date or POSIX
return(result)
}
xx <- pippo(...)
#mode(attributes(xx)$row.names) is now character !!!!
This is new to 2.3.1 (and to 2.3.0 i suppose), i.e. everything worked like a
charm in 2.2.1; it looks like a bug to me (but might notbe), and I have not
been able to find any reference to such a problem in the archives (which is
strange,
but I might have got blind).
Any idea pls?
Thanks a lot in advance
