I was wondering if someone would be willing to help me with creating
user-defined types. I've been using Julia for about two years now but I am
new to the idea of creating custom types. I'm trying to create a population
of agents/individuals in a simple epidemiological simulation. I would like
the population of individuals to be structured as a 2 dimensional array
with rows as individuals and columns as properties. This would be somewhat
similar to a DataFrame, but potentially more flexible. I want to be able to
index an individual like so: population[1]. This woud list all of the
information for individual 1. I would also like to be able to look at an
attribute across individuals: population.infected or population[:infected].
At the same time, I would like to have to flexibility of using an array to
keep track of individuals: typeof(population.history[1]) is Array{Int64,1}.
Based on existing documentation and examples, I have only been able to
create individuals but cannot figure out how to create a population as
described above:
type Person
infected::Int64
vaccinated::Int64
dead::Int64
history::Array{Int64,1}
end
Any help would be greatly appreciated.
