Hi Team,
This scenario may have come across a number of times however i checked
nabble & SO and couldn't find a solution hence request assistance.
I have a date variable in my data-set eir. The class of this var was
character while i had read the file in r studio. Example of date - 05-30-16
To change this i have used eir$date<- as.Date(eir$date, "%m-%d-%y"). This
converts it to a date variable. However when i check few obs
with head(eir$date) all the results are <NA>.
I think you don't have character data like that, because I see
> as.Date("05-30-16", "%m-%d-%y")
[1] "2016-05-30"
I'd guess eir$date is really a factor, because character data is
frequently changed to factor automatically. If that's the case, this
should work for the conversion:
as.Date(as.character(eir$date), "%m-%d-%y")
If that doesn't work, you'll need to post something reproducible.

I also need to create weekdays from this date variable but until i get this
resolved i cant find a weekday. For weekday i have used:
eir$week<- (eir$date)
eir$week<- weekdays(as.Date(eir$week))
class(eir$week)
eir$week<- as.factor(eir$week)
head(eir$week)
Head of this eir$week results again as expected in <NA> but shows Levels:
Friday Monday Saturday Sunday Thursday Tuesday Wednesday
Not sure what i should do here. Kindly suggest.
