> I had put it in a csv in my desktop using
write.csv(ashdata,"D:/ashdata1.csv")

Then I tried to access the csv using read.csv("D:/ashdata1.csv")

but when I accessed the data , the "date" format changed to numeric
expression like

10 ,20 ,30 ,

Can anybody suggest a simple way to handle Dates in R , could not find any
function .

Sorry for such a basic Questions.


Thanks You

The initial display looks like an xts or zoo data-object. The dates would be
row.names and the interior entries part of the coredata matrix. `write.csv`
might not be the proper vehicle for saving such an object.
It sounds like you got the dates read in as character variables which
unfortunately means they were probably automatically converted to factors, given
the stringsAsFactors is an option that is TRUE by default.
