Usage

First of all, obtain API credentials from Yummly.com. After that you can use save_yummly_credentials() to persist the application ID and application key between queries, or supply them directly to search_recipes() and get_recipe() functions.

Search Recipes

search_recipes() function corresponds to Search Recipes API call and is used to search for recipes fitting certain criterias. Example search response. The simplest call looks like this:

search_recipes('bacon')

YummlyR supports wide variety of criteria:

• require_pictures: if TRUE, only to return recipes with photos.
• allowed_ingredient: ingredient that all search results must include.
• excluded_ingredient: ingredient that all search results should not contain.
• allowed_diet: search results will only include recipes whose ingredients are allowed for that diet.
• allowed_allergy: only include recipes whose ingredients are allowed for that allergy.
• allowed_cuisine: search results will only include recipes with that cuisine.
• excluded_cuisine: search results will only exclude recipes with that cuisine.
• allowed_course: search results will only include recipes with that cuisine.
• excluded_course: search results will only exclude recipes with that cuisine.
• excluded_holiday: search results will only exclude recipes with that holiday.
• max_total_time: search for recipes that do not exceed a specified max total cook + prep time in seconds
• max_results: number of results to return.
• start: start with specific result in search.
• nutrition: set the range of allowed values for a given nutrition attribute (see below for the list of supported nutrition attributes) by setting a min and/or a max.
• flavor: set the ranges for taste attributes (this corresponds to the taste sliders on the Yummly.com search page). The values of min and max are between 0 and 1.
• facet_field: facet counts for ingredient and diet. When this parameter is called, the response will include a facetCounts object that lists the matching diets or ingredients and how many results match each diet or ingredient.

For example,

search_recipes("onion soup", allowed_ingredient = "bacon")

will return onion soup recipes that contain bacon. More detailed expanations of Yummly's Search API with example can be found here.

Note that allowed values for ingeredient, diet, allergy, cuisine, course, holiday, nutrition and flavor are defined by Yummly.com metadata and saved inside the package for convenience. Available metadata can be accessed with get_metadata():

get_metadata('holiday')

This returns a data.frame with information about available holiday keywords.

Fetch a recipe by its ID. Example recipe response. For example:

get_recipe("French-Onion-Soup-The-Pioneer-Woman-Cooks-_-Ree-Drummond-41364")

This returns detailed information about French Onion Soup French Onion Soup.
