tidyUSDA, an interface to USDA Quick Stats data with mapping capabilities.
Overview
tidyUSDA provides the R user with a consistent API to pull USDA census and survey data from Quickstats.
getQuickstat()lets you pass values to the fields you see on the QuickStats website, as well as include a simple features (SF) geometry field for the county or state level.View({parameter name})lets you view QuickStats all available values for a given field (which you would input into getQuickstats(), preferably with copy paste)plotUSDA()provides a quick way to plot your data if you set geometry = TRUE

Usage
Check out the vignette with:
vignette("using_tidyusda")You first need to grab a free API token from the USDA at their Quickstats website.
library(tidyUSDA)
# Save your API token to a variable, or better yet, use the keyring package to store it securely
key <- '1234-abcd'
# View all parameter names for the 'program' field
View(tidyUSDA::allProgram)
# Get count of operations with sales in 2017
ops.with.sales <- tidyUSDA::getQuickstat(
sector=NULL,
group=NULL,
commodity=NULL,
category=NULL,
domain=NULL,
county=NULL,
key = key,
program = 'CENSUS',
data_item = 'CROP TOTALS - OPERATIONS WITH SALES',
geographic_level = 'COUNTY',
year = '2017',
state = NULL,
geometry = T,
lower48 = T)
# Plot this data for each state
tidyUSDA::plotUSDA(df = ops.with.sales)The last function returns this ggplot choropleth:
