r - Convert numeric to date

Question

I'd like to convert this type of numeric values to a date but it doesn't work.

20100727 for instance

I tried to convert the numeric to character and applied this :

as.Date("20100727", "Y%d%m")

but it doesn't work.

How can I do ?

Answer 1

You were setting wrong order of month and date values (in your code was Year, Date, Month, should be Year, Month, Date).

as.Date("20100727", "%Y%m%d")
[1] "2010-07-27"
