Hi I have the following factor of dates that I want to converted to Date class so I can extract the month
> test.date
 [1] 14/05/2012 14/05/2012 14/05/2012 14/05/2012 14/05/2012 14/05/2012
 [7] 14/05/2012 14/05/2012 14/05/2012 14/05/2012
201 Levels: 01/10/2012 01/11/2012 01/12/2012 02/07/2012 ... 28/09/2012
I use code below
ntest.date<-as.Date(test.date,'%d/%m/%y')

but the output has the wrong year, and the reverse order
ntest.date
 [1] "2020-05-14" "2020-05-14" "2020-05-14" "2020-05-14" "2020-05-14"
 [6] "2020-05-14" "2020-05-14" "2020-05-14" "2020-05-14" "2020-05-14"

What am I doing wrong?
I dare not say the word 'bug'
Thanks
