R change integer to three integers

Question

I have this number

20101213 which is a representation of this data 2010 Dec 13th I want to extract the year, month and day numbers from that nu

Answer 1

If you don't want to deal with string representation you could also just use mod function like this:

# using mod
year  = floor(value/10000)
month = floor((value %% 10000)/100)
day = value %% 100

Which will then extract the relevant parts of the number as expected.
