Method for converting openaq_licenses_list to data frame.

Usage

# S3 method for class 'openaq_licenses_list'
as.data.frame(x, row.names = NULL, optional = FALSE, ...)

x: A list of licenses as returned from list_licenses.
row.names: NULL or a character vector giving the row names for the data frame. Missing values are not allowed.
optional: logical. If TRUE, setting row names and converting column names (to syntactic names: see make.names) is optional. Note that all of R's base package as.data.frame() methods use optional only for column names treatment, basically with the meaning of data.frame(*, check.names = !optional). See also the make.names argument of the matrix method.
...: additional arguments to be passed to or from methods.

A data frame class of the licenses results, with the following columns:

id: Numeric. The licenses identifier.
name: Character. The license name.
commercial_use_allowed: Logical. Indicates whether commerical use is allowed under the license terms.
attribution_required: Logical. Indicates whether attribution is required under the license terms.
share_alike_required: Logical. Indicates whether share-alike is required under the license terms.
modification_allowed: Logical. Indicates whether modification is allowed under the license terms.
redistribution_allowed: Logical. Indicates whether redistribution is allowed under the license terms.
source_url: String. The URL of the license as listed by the upstream source.

The data frame also includes a meta attribute from the original openaq_licenses_list.
