function to create multiple matrices
Hi All,
If given a dataframe (long form) with Year, Species, and Location,
How would I write a function that would create a unique matrix of Species &
Location for each Year?
What I've tried doing is the following:
data #dataframe
dataT<-table(data$Species,data$Location,data$Year) #creates tables of
Species vs Location for each Year
But I'm encountering issues individually
