get_nassqs_data: Get USDA NASS data and return a data frame

In opus1993/rnassqs.extra: Extend the rnassqs USDA NASS ‘Quick Stats’ API package

Description

A wrapper function for the rnassqs package, get_nassqs_data makes a HTTP GET request to the USDA-NASS Quick Stats API and returns a subset of the data parsed as a tibble.

Usage

get_nassqs_data(
  comm_list = c("CORN", "COTTON", "SOYBEANS", "WHEAT", "SUGARCANE", "SUGARBEETS",
    "SORGHUM", "RICE", "BARLEY"),
  start_year = 1990L,
  end_year = 2019L
)

Arguments

comm_list	A list of 'nassqs' commodities. All possible values available from nassqs_param_values()
start_year	A start year integer
end_year	An end year integer

Details

• The default comm_list includes CORN, COTTON, SOYBEANS, WHEAT, SUGARCANE, SUGARBEETS, SORGHUM, RICE, BARLEY, and APPLES

• The default date range is 1990 through 2019

• The core 'rnassqs' function nassqs() is mapped with 'purrr' to be called for each combination of year and commodity. Larger data requests will require more time

Examples

library(tidyverse)

comm_list <- c("CORN","WHEAT")
start_year <- 2018L
end_year <- 2019L

get_nassqs_data(comm_list, start_year, end_year)
