• Fixed package documentation crossreference issues

• Fixed package documentation issues arising from changes in roxygen
• Made package startup message align with version number

• Removed deprecated mapping functions to address #45 the sunsetting of maptools
• Cleaned up old and redirected URLs

• Update to avoid CRAN check warnings on some platforms

• Updated unit tests to avoid warnings associated with the new random number generator in R 3.5.3

• In max_mis, there is an if predicate that checks if a class is of an invalid type. Because R objects can have multiple classes, this statement relies on the R semantics that the first value of the logical vector returned by the predicate is used. This is a feature R-core is looking to remove as it has considerable performance penalties. This check is now wrapped in any(), which evaluates TRUE if any value in the logical vector is TRUE.

• New function isid for determining if a combination of variables uniquely define the rows in a dataframe

• Fixed error in statamode with method = "last" thanks to PR from @larcat
• Fix import compatibility with ggplot2

• Minor fixes for CRAN repository compliance in dependencies contained in vignettes

A CONTRIBUTING.md file modeled after the excellent example in the rio package by @leeper

• Fix compatibiltiy issue for leading_zero function with latest version of R

• Thanks to new and better tools the mapping functions mapmerge and ggmapmerge are no longer necessary thanks to geom_map and further enhancements to ggplot2

• Revise readme.rmd to include plots in package build

• Thanks to new ggplot2 theme options, the theme_dpi functions are now just wrappers for theme_bw

• Fixed logical test in age_calc (GH #32)
• Fixed issue with calls to library in examples (GH #33)

• Compatibility with ggplot2 and roxygen updates

• nth_max performance is improved thanks to use of partial sort contributed by @sgibb

This is a major update including removing little used functions and renaming and restructuring functions.

• A new package vignette is now included
• nth_max function for finding the nth highest value in a vector
• retained_calc now accepts user specified values for sid and grade
• destring function deprecated and renamed to makenum to better reflect the use of the function
• crosstabs function exported to allow the user to generate the data behind crosstabplot but not draw the plot

• dropbox_source deprecated, use the rdrop2 package
• plotForWord function deprecated in favor of packages like knitr and rmarkdown
• mapmerge2 has been deprecated in favor of a tested mapmerge
• mosaictabs.labels has been deprecated in favor of crosstabplot

• nsims in gelmansim was renamed to n.sims to align with the arm package
• Fixed bug in retained_calc where user specified sid resulted in wrong ids being returned
• Inserted a meaningful error in age_calc when the enddate is before the date of birth
• Fixed issue with age_calc which lead to wrong fraction of age during leap years
• lag_data now can do leads and lags and includes proper error messages
• fix major bugs for statamode including faulty default to method and returning objects of the wrong class
• add unit tests and continuous integration support for better package updating
• fix behavior of max_mis in cases when it is passed an empty vector or a vector of NA
• leading_zero function made robust to negative values
• added NA handling options to cutoff and thresh
• Codebase is now tested with lintr to improve readability

• moves_calc function from Jason Becker
• gelmansim function to do post-estimation prediction on new data from model objects using functionality in the arm package
• statamode updated to work with data.table
• age_calc function from Jason Becker given new precision option
• lag_data function to create groupwise nested lags quickly

• unit tests for decomma, gelmansim, and statamode using testthat package

• new functions for building maps with shapefiles including

  • mapmerge to merge a dataframe and a shapefile, and
  • ggmapmerge to convert this to a document for making a map in ggplot2

• statamode updated to allow for multiple methods for handling multiple modes

• emove_stars deleted and replaced with remove_char to allow for users to specify an arbitrary character string to be removed

• add plotForWord function to export plots in a Windows MetaFile for inclusion in Microsoft Office documents

• add age_calc function to allow calculating the age of a vector of birthdates relative to the current date (h/t Jason Becker)

• fix typos in documentation
• fix startup message behavior
• reduce dependencies of the package dramatically so loading is faster and more lightweight
