USStatesBG border group datasets to support use with U.S. States amd D.C. Areas

Description

The micromapST function has the ability to generate linked micromaps for any geographical area. To specify the geographical area, the bordGrp call argument is used to specify the border group dataset for the geographical area. When micromapSt function is used to micromap the U.S. States and DC areas, no border group needs to be specified. The USStatesBG border group is the same as the original sub-areas (states and DC) and boundaries used by the all previous versions of the micromapST package. By default micromapST loads the area fullnames, abbreviations, IDs and boundaries files for 50 U. S. states and the District of Columbia for the processing of user data and the creation of the requested linked micromap.

Details

The USStatesBG border group contains in the following data.frames:

areaParms: - specific parameters associated with this border group
areaNamesAbbrsIDs: - containing the names, abbreviations, numerical identifier and alias matching string for each of the 51 U. S. States and D.C.
areaVisBorders: - the boundary point lists for each of the 51 States and D.C..
L2VisBorders: - the boundaries for the U. S. states and DC. It is identical to areaVisBorders data.frame.
RegVisBorders: - the boundaries for the 4 U. S. census regions
L3VisBorders: - the boundary of the U.S

Refer to the section on the border group data.frames for a detailed discussion on the formats and usage of each of the above data.frame.

In this border group, there are 51 areas (states and DC) and information and names in the areaNamesAbbrIDs data.frame and there boundaries in the areaVisBorders data.frame. The L2VisBorders data.frame contains a copy of the areaVisBorders data.frame to allow heavier overlaying of the state and DC boundaries during mapping. The RegVisBorders data.frame contains the information and boundaries for the 4 U. S. census regions. The L3VisBorders dataset contains the information on the boundaries of the U.S.

Alaska and Hawaii are relocated to below California and Alaska is reduced in size by 50

All data must be tagged with the name, abbreviation or id strings to be able to find the associated boundaries information. With the USStatesBG only, the package will accept several variations on the full name for DC. They include: Washington, D.C., District of Columbia, and D. C. All can be with or without punctuation and upper and lower case. When detected, the name is translated to "DC".

The dataRegionsOnly call parameter can be set to TRUE to request the package to limit the mapping to only states in regional areas where data is being mapped and omit states and regions that do not contain data. This allows the caller to focus the micromaps on one of the four (4) census regions: NorthEast, South, Midwest, or West.

The rowNames = alias, rowNames = alt_ab are not support in the USStatesBG border group.
