usmap 0.6.2

Released Tuesday, June 13, 2023.

Bug Fixes

• Replace retired packages maptools and rgdal with sp and sf, see Issue #57 and Issue #70.

usmap 0.6.1

Released Saturday, November 12, 2022.

Bug Fixes

• Fix failing plot_usmap tests, see Issue #58.
• Fix aes_string and size deprecation in ggplot2, see Issue #59.

usmap 0.6.0

Released Sunday, February 27, 2022.

New Features

• Add input_names and output_names parameters to usmap_transform, see Issue #33.
• Add sortAndRemoveDuplicates parameter to fips_info, see Issue #47.
• The default (FALSE) value changes existing behavior, to retain existing behavior, change the parameter value to TRUE.

Improvements

• Improve map resolution.
• More polygons are shown, this has a marginal increase on the data set file sizes but it is negligible.
• Add shape file update history, see Issue #30.
• Extract map data frame to external usmapdata package to reduce usmap package size, see Issue #39.
• All existing functions (including us_map()) should continue to work as usual.
• Add data format examples for plot_usmap to "Mapping" vignette, see Issue #42.

Bug Fixes

• Fix CRS warnings, see Issue #40.
• Fix plot_usmap() issue when provided data has "values" column, see Issue #48 and this Stack Overflow question.

usmap 0.5.2

Released Wednesday, October 7, 2020.

• Update links in documentation.

usmap 0.5.1

Released Wednesday, October 7, 2020.

• New website for the package: https://usmap.dev
• Lightweight landing page containing useful information, links, and examples of usmap usage.
• state can now be omitted when using fips(). In this case, all available FIPS codes are returned, sorted by state abbreviation, see Issue #28.
• fips can now be omitted when using fips_info(). In this case, all available states are returned, sorted by state abbreviation, see Issue #28.
• Fix duplicate coordinates from being removed during usmap_transform (if value columns differ), see Issue #32.
• Prevent warnings introduced by ggplot2 v3.3.0, see Issue #35.
• Set minimum R version to 3.5.0. Versions lower than this do not support the latest version of the rgdal package.

usmap 0.5.0

Released Friday, September 13, 2019.

New Features

• Ability to include county name labels on county maps, see Issue #14.
• They currently work the same as state labels except they include the full county name (excluding the word "County").
• Ability to pass ggplot2::geom_polygon() parameters to plot_usmap(), see Issue #15.
• This is a breaking change and removes the lines parameter. The previous defaults of color="black", fill="white", and size=0.4 are maintained and will be used for any of those parameters that are omitted.
• Refer to the ggplot2::geom_polygon() documentation for more information.
• The following aesthetics are supported: alpha, colour/color, fill, linetype, size
• This feature provides more direct control over the appearance of plots.
• Ability to exclude counties and states with new exclude parameter in us_map, map_with_data, and plot_usmap, see Issue #19.
• New function (usmap_transform) to transform longitude/latitude point data frames into coordinate reference system that matches the plotted map, see Issue #21.
• Also includes usmap_crs() to easily access the coordinate reference system used by the package.

Improvements

• In the data frames provided by us_map(), long and lat have been renamed to x and y, respectively, see Issue #16.
• This should not affect the behavior of plot_usmap() but will be a breaking change for any code that relies on us_map().
• Added contributing guidelines and templates, see Issue #24.
• These can be see in the .github folder.

usmap 0.4.0

Released Sunday, September 16, 2018.

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

Released Sunday, June 3, 2018.

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

Released Tuesday, August 15, 2017.

Improvements

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

Bug Fixes

• Allow data passed to map_with_data and plot_usmap to contain FIPS codes with missing leading zeros.
• This usually occurs when the codes are read as numeric from a .csv file.

usmap 0.2.0

Released Saturday, April 29, 2017.

• Add map_with_data function for adding user-defined data to map data.
• Add ability to plot map with data automatically (utilizes new map_with_data function).

Released Sunday, January 29, 2017.

• First release

Main features

• Retrieve US map data frame for merging with data and plotting
• Lookup FIPS codes for states and counties (reverse-lookup as well)
• Map plotting convenience method (uses ggplot2)
