Hello, I plot the abundance of a species in relation to the date. To
have the
date as a continous variable I put it in the format "standard" in
excel
(f.ex. 39939 means 06.05.2009). R uses 39939 on the x axis, but I
would like
to have "06.05". I tried to use as.Date as suggested in some
discussion but
I don't manage to use it, the returned date is not correct. Do you
have any
clue? thank you
You may need to do some jiggling around because R doesn't agree with
that number of days since the beginning of the last century:
> as.Date(39939, origin="1900-01-01")
[1] "2009-05-08"
Then you need to look at docs re: the formating of date objects. Some
code might move this process along.
