R help - May 2009 - dates from Stata's .dta to R's .Rdata: become character

Dear Sir/Madam,
I converted the .dta into .Rdata with the foreign library read.dta. However,
when I use fix() I get the message that the dates are discarded.
Before fix(), class(dateX) gives 'dates' as class; after fix()
class(dateX)
gives 'character'
Why is that?

Best regards,

Rob Bakker

Because fix() can't handle date columns in a data frame. Look at ?fix and
click the link for edit.data.frame :  " At present, this only works on
simple data frames containing numeric, logical or character vectors and
factors, and numeric, logical or character matrices. Any other mode of
matrix will give an error, and a warning is given when the matrix has a
class (which will be discarded)."

I hope this helps,
 John
