usmap 0.4.0

New Features

• Ability to include state abbreviation labels in state maps, see Issue #9.
  • e.g. plot_usmap(labels = TRUE)
• Add US Census Bureau regional divisions as constants for quick plotting of certain regions.
  • e.g. plot_usmap(include = .northeast_region)
  • The provided regions and divisions can be seen on this map by the US Census Bureau.
• Allow ability to include only certain states while viewing county map, see Issue #11.
  • e.g. us_map("counties", include = "TX") or plot_usmap("counties", include = c("AZ", "NM"))

Improvements

• Vectorize counties in fips, see Issue #10.
  • e.g. fips("NJ", c("Bergen", "Hudson"))
• Allow all columns in the data frame that's passed to map_with_data() or plot_usmap() to be preserved.

Bug Fixes

• Add Kusilvak Census Area (FIPS code 02158), replaces Wade Hampton Census Area (FIPS code 02270).

usmap 0.3.0

Improvements

• Update shape files to 2017 versions.
• Improvements to fips and fips_info:
  • Vectorization support (e.g. enter multiple states in fips to receive a vector of corresponding FIPS codes)
  • e.g. fips(c("AK", "AL")) or fips(c("Alaska", "Alabama"))
  • Mixed abbreviations and full names are also supported: fips(c("AK", "Alabama"))
  • Improved warning and error messages.
• Allow data to be specified by state abbreviation or full name in plot_usmap and map_with_data (instead of just by FIPS code).
  • The data frame passed to plot_usmap or map_with_data (via the data = parameter), can now be a two column data frame with columns "fips" and "values" or "state" and "values".

usmap 0.2.1

Improvements

• Standardize documentation language.
• Improve descriptiveness of error messages and warnings.

• Add ability to plot map with data automatically (utilizes new map_with_data function).
