commodity_lookup() throwing error, related to param return_char

[ChrisMuir]

When a single lookup value is passed, the functions works great:

commodity_lookup("trout", commoditydf, return_char = FALSE)

However when multiple lookup values are passed, AND return_char is set to FALSE, the function throws an error:

commodity_lookup(c("tomato", "trout"), commoditydf, return_char = FALSE)

results in:

Error in function_list[[k]](value) : 
  'names' attribute [2] must be the same length as the vector [1]

The desired output is a named list of length two.

I'm working on patching this bug now.

This issue has been fixed in commit #56

Returning to the example from above:

commodity_lookup(c("tomato", "trout"), commoditydf, return_char = FALSE)

now returns:
