I'm currently trying to convert a day of the year (DOY) value with decimals to datetimes. What I mean by this for example, the value 32.5 represents the date Feburary 1st, 12pm UTC. I've looked all over and I can't seem to find anything to convert this properly. Any suggestions would be great.
An example dataframe for code
df<-data.frame("DOY" = c(32.5, 33, 33.5), "Value" = c(5,10,7))
