Hi,
I have some problems with as.Date function.
After I applied as.Date for my data, "2010" changed to "2020" as below
Where am I wrong?
You used %y (two-digit year, here: "20" and then expanded to "2020")
instead of %Y (four-digit year, here "2010").
Using as.Date(x,"%m/%d/%Y") yields the desired result.

Thanks

x=c("11/16/2010","11/17/2010","11/18/2010","11/19/2010")
x=as.Date(x,"%m/%d/%y")
x
[1] "2020-11-16" "2020-11-17" "2020-11-18" "2020-11-19"
my R veision is 2.12.2.
