[R] Clarification about data/weekday conversion

[t.k. t.k.]

Hi everyone
This is a general question.
I have imported a "Dates" variable as character. I used the "as.Date"
command and convert it to Date,format..

I want to change the display of the date to weekday (e.g., I want my time
series to be instead of 15-04-2010 as Friday-04-2010). I used the "format"
command but the variable reverts back to character. Is there a way to
change the day to weekday and my variable remain a "Date,format..."
variable?

these are the two lines I used as code

Hpc$Date1<- as.Date(Hpc$Date, "%d/%m/%Y")

Hpc$Date1<-format(Hpc$Date1, "%a %b %d %Y")

thanks in advance
