Hello, I am having trouble figuring out how to convert a Day of Year integer back into a Date format. For example I have the following:
date <- c('2008-01-01','2008-01-02','2008-01-03','2008-01-04','2008-01-05','2008-01-06','2008-01-07', '2008-01-08','2008-01-09','2008-01-10','2008-01-11','2008-01-12','2008-01-13','2008-01-14','2008-01-15', '2008-01-16','2008-01-17','2008-01-18','2008-01-19','2008-01-20','2008-01-21','2008-01-22','2008-01-23') ## this is then converted into a number corresponding to the day of the year like so: dayofyear <- strptime(date, format="%Y-%m-%d")$yday + 1 ## Now my question is how do I get back to a date format (obviously omitting the year). ## The end result is that I'd like to be able to have axis labels as something like "Month-Day" or just "Month" ## instead of just an integers which isn't always intuitive for people but I can't seem to figure out how to tell R ## to recognize an integer as a date. Any suggestions? Many thanks in advance!
