[julia-users] how to use map( myfun(d::Dict), mydicts )

[Florian Oswald]

Hi!

I want to iterate over a collection of dicts and evaluate a function that 
takes one Dict at a time. In R-speak I have a list of lists and want to 
lapply my function - which takes a list as input - for each sublist:

function dfun(d::Dict)
       println(collect(keys(d)))
       println(collect(values(d)))
       end

# my dict of dicts
d = [1 => ["a" => 1.1], 2 => ["b" => 3.12]]
[2=>["b"=>3.12],1=>["a"=>1.1]]

# works?
julia> dfun(d[1])
ASCIIString["a"]
[1.1]

# maps?
map(dfun,d)
ERROR: no method dfun((Int64,Dict{ASCIIString,Float64}))
 in map at abstractarray.jl:1183


What's the correct way of doing this? I'm surprised it sends 
(Int64,Dict{ASCIIString,Float64}) 
to the funciton and not just Dict{ASCIIString,Float64}
