[R] Limit

[Val]

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.
