Data and code from: Mixed infection, risk projection and misdirection: Interactions among pathogens alter links between host resources and disease

vir.div.np.csv: data from the experiment. 
vir.div.np.R: commented R notebook the runs all of the analyses presented in the paper; reads data the csv

definitions of columns in the csv:
n: level of experimental nitrogen ferilization (1=lowest, 2=intermediate, 3=highest)
p: level of experimental phosphorus ferilization (1=lowest, 2=intermediate, 3=highest)
rep: unique identifier for replicate (individual host) within the combined nxp treatment
vir: identity of the virus 
div: level of experimental inoculation, either "single" or "mix"
vec: identity of the aphid vector carrying the virus(s) (Rpa = R. padi; Sav = S. avena; Sgr = S. graminum; Mix=mix)
dateofpcr: date when the polymerase chain reaction was run to diagnose infection
inf: whether the host was infected (y=yes, n=no)
bandstrength: strenth of the gel band for infection diagnosis
source: unique identifier within each virus to signify the leaf from which the aphid acquired the virus (A-O; unique within each virus)
notes: in mixed virus treatments, indicates whether a different source leaf identifer applies to one or more of the three viruses as reported under "source" (e.g., if R padi and S. graminum acquired RPV and SGV from respective leaves RPV leaf A and SGV leaf A, but S. avena acquired PAV from PAV leaf B)
more notes: noted if aphids were placed on the third (rather than second) leaf; and if the leaf was mechanically damaged during the process of removing aphids (PD)
date down: date which the experiment was taken down
