I have a file that reads like this:
How much R do you know? Are you still at the stage where you need
basic help reading a file into a session?
Species,Year,Julian_day
Alnus_glutinosa, 1873, 123
Sorbus_aucuparia, 1873, 122
....(more species...)
Alnus_glutinosa, 1874, 134
Sorbus_aucuparia, 1874, 143
....(more species and years)
Is there a way to plot this as julian day over years so that each
species
get a different color?
If (as is quite likely) that species variable is (or will be)
actually a factor, you could use as.numeric(Species) as a vector for
the color argument.
with(dfname, plot(Julian_day, Year, col=as.numeric(Species)))
Also is it possible to convert this data into the format:
Alnus_glutinosa, Sorbus_aucuparia,....(more species)
123 122
134 143
...(more years)
?reshape
package::reshape2
(and possibly other tabulating, time-series, and recoding options,
depending on all those devilish details you have unfortunately omitted.)
Then I could attatch a time series to the data.
