Ag Land, Incl Buildings - Revised

Previous release JOSS submission included citations with errors. Citations were not needed so they are dropped in this release.

Ag Land, Incl Buildings

Update for JOSS submission, and include a feature request to get valid values of a parameter based on a set of query criteria. For example, user can now query the valid parameters for commodity_desc for a specific county and year instead of for all geographies and years.

Ducks - Operations with Sales

This release incorporates improvements to usability and documentation resulting from the rOpensci review process, including:

Queries no longer require listing

Queries can be made both by passing a list of parameters or the parameters themselves directly. These two queries are equivalent:

# Method 1: specify query parameters as function arguments
rnassqs::nassqs(commodity="APPLES", year__GE = 2012)

# Method 2: specify a list of parameters as a single function argument
params <- list(commodity = "APPLES", year__GE = 2012)
rnassqs::nassqs(params)

Key management is much simplified

Previously rnassqs managed keys in an unnecessarily complicated way. Now the package simply checks if the NASSQS_TOKEN environmental variable is set, and if not suggests how to set it.

Documentation improvements

Many changes to the Getting Started vignette and to function documentation should improve ease of use.
