I have a package that should be called by functions to access mathematica data sources
In my example program i do want a pull down of the states. In the example it seems easier because the list is already defined by the data source.(?).
i need the data to be in a list but also to have quotes around it so when it is stuffed into the function the correct syntax is written. i have attached both. i get an error about the list not being properly defined.
usingWhere toLive.nb
<< WhereToLive`
MyManipulation[states]
the package whereToLive.m
BeginPackage["WhereToLive`"]
MyFunction::usage =
"MyFunction[state] shows the shape of state and a list of cities.Select a city
to see information";
MyManipulation::usage="MyManipulation[set] sets up a demonstration that shows A group of cities
in a state in set,and lists cost of living data about them.";
Begin["`Private`"]
states_ = {"\"Alabama\"","\"Ohio\"","\"Florida\""}
MyFunction[states_] := CityData[{Large,states,"UnitedStates"}];
MyManipulation[set_:"UN"]:= Manipulate[MyFunction[states],{CityData[Large,set,"UnitedStates"]}];
End[ ]
EndPackage[ ]
