Hi All,
I am reading data file ( > 1B rows) and do some date formatting like
dat=fread(mydatafile)
dat$date1 <- as.Date(ymd(dat$date1))
However, I am getting an error message saying that
Error: cons memory exhausted (limit reached?)
The script was working when the number rows were around 650M.
Is there another way to handle a big data set in R?
Thank you.

Hello,
fread works but as.Date(ymd(.)) does not?
You probably don't need both date coercion functions, get rid of one of
them and try again.
dat$date1 <- ymd(dat$date1)
or
dat$date1 <- as.Date(dat$date1)
Hope this helps,
