as.Date not returning the date part from a POSIXt object

Question

I am trying to get the date part of a date-time POSIXt object in R I get a number instead.

Here is my data:

    y <- "2017-01-03 19:59:00"

Using following code:

    as.Date(as.POSIXct(y))

I get this number: 17169. I am in Eastern Time Zone (UTC-05:00) and have checked to make sure y is a POSIXt class. I am out of options and any help is appreciated.

What exactly do you want as a result? If it's just `2017-01-03` you can do `sub(' .*', '', y)` — C. Braun, Apr 04 '18 at 18:48
@C.Braun I want the date part in a date format. The way you mentioned will create a character. — Fatima, Apr 04 '18 at 18:51

That is weird. It worked fine on my machine previously as well. I though maybe some packages have been updated that I am not aware of and it does not work properly anymore. – Fatima Apr 04 '18 at 18:54
well. I figured it out. I was using the conversion in an ifelse function and that was the bug with ifelse. as I switched to if-else the problem is resolved. Thanks everyone – Fatima Apr 04 '18 at 18:59
