Method for converting openaq_manufacturers_list to data frame.

Description

Method for converting openaq_manufacturers_list to data frame.

Usage

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

Arguments

x	A list of manufacturers as returned from list_manufacturers.
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.

Value

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

id

Numeric. The manufacturers identifier.

name

Character. The name of the manufacturer.

instrument_ids

Character. A comma delimited list of instrument identifiers manufactured by the manufacturer.

instrument_names

Character. A comma delimited list of instrument names manufactured by this manufacturer.

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

Examples

manufacturers <- list_manufacturers(as_data_frame = FALSE)
as.data.frame(manufacturers)
