Value

This function returns data of specific photos matching search parameters.

Arguments

api_key

Flickr API key. If api_key is `NULL`, the function uses [getFlickrAPIKey()] to use the environment variable "FLICKR_API_KEY" as the key.

user_id

The NSID of the user with photos to search. If this parameter is NULL passed then all public photos will be searched.

tags

A vector of tags to search for.

license_id

The license id for photos. For possible values see the Flickr API method flickr.photos.licenses.getInfo or see details for more information.

sort

Order to sort returned photos. The possible values are: "date-posted-asc", "date-posted-desc", "date-taken-asc", "date-taken-desc", "interestingness-desc", "interestingness-asc", and "relevance" The trailing "-asc" or "-desc" indicator for sort direction is optional when using the desc parameter.

desc

If `TRUE`, sort in descending order by the selected sort variable; defaults to `FALSE`.

bbox

A object of class `bbox` or a numeric vector with values for xmin, ymin, xmax and ymax representing the bottom-left corner of the box and the top-right corner.

img_size

A character string with the abbreviation for one or more image sizes ("sq", "t", "s", "q", "m", "n", "z", "c", "l", or "o"). If a single img_size is provided the url, width, and height columns are renamed (e.g. img_url instead of url_sq) and an img_asp column is added to the results; defaults to `NULL`.

extras

A vector of extra information to fetch for each returned record. Currently supported fields are: c("description", "license", "date_upload", "date_taken", "owner_name", "icon_server", "original_format", "last_update", "geo", "tags", "machine_tags", "o_dims", "views", "media", "path_alias", "url_sq", "url_t", "url_s", "url_q", "url_m", "url_n", "url_z", "url_c", "url_l", "url_o")

per_page

Number specifying how many results per page to return. Default 100 results per page. Maximum of 250 if `bbox` provided or 500 otherwise.

page

Number specifying which search results page to return. Default is page 1 of results returned.

...
