The manystates::states datacube is a list containing 3 datasets: ISD, GW, and GGO.
It is a work-in-progress, so please let us know if you have any comments or suggestions.
Format
- ISD:
A dataset with 499 observations and 36 variables: stateID, StateName, Begin, End, StateNameAlt, Latitude, Longitude, StartType, EndType, cowID, cowNR, ISD_Category, Region, Start_Am, EStart_Am, Declare, DecDate, Population, ..., VioEnd, and VioEnd_Am.
- HUGGO:
A dataset with observations and variables: .
- GW:
A dataset with 216 observations and 7 variables: stateID, StateName, Begin, End, StateNameAlt, cowID, and cowNR.
For more information and references to each of the datasets used,
please use the manydata::call_sources() and manydata::compare_dimensions() functions.
