Let’s say that I have a date in R and it’s formatted as follows.
date
2012-02-01
2012-02-01
2012-02-02
Is there any way in R to add another column with the day of the week associated with the date? The dataset is really large, so it would not make sense to go through manually and make the changes.
df = data.frame(date=c("2012-02-01", "2012-02-01", "2012-02-02"))
So after adding the days, it would end up looking like:
date day
2012-02-01 Wednesday
2012-02-01 Wednesday
2012-02-02 Thursday
Is this possible? Can anyone point me to a package that will allow me to do this?
Just trying to automatically generate the day by the date.
