• Adds functions get_group, get_YiGmin1, and get_Yi1 as utility functions for manipulating data. This is especially useful for settings with staggered treatment adoption.

  • Add functions get_lagYi and get_first_difference as more utility functions for working with panel data.

  • Add function get_Yit which recovers outcomes in period t for all units in a panel.

  • Restore default of makeBalancedPanel to return a data.frame rather than a data.table. New function argument return_data.table allows for returning a data.table if this is the desired functionality from the user.

  • only execute examples for subsample and blockBootSample if plm package is available (thanks Achim Zeileis)
  • faster version of panel2cs2 (thanks Kyle Butts)
  • added Rcpp multiplier_bootstrap function

  • added TorF function, a vectorized version of isTRUE

  • allow for additional arguments in combineDfs function

  • changed package maintainer contact information

  • added source_all function

  • added getElementList function
  • removed dependency on plm and formula.tools

  • add function blockBootSample for block bootstrapping with panel data

  • add option in makeDist to force the values of the distribution function be between 0 and 1

  • Update rhs.vars to fix bug related to formulas like y~x+I(x^2)

  • Update toformula to allow for no right hand side variables

  • Added function to take distribution functions (ecdf objects) and turn them into step functions for the quantiles.

  • Improved code for working with formulas

  • Added function for obtaining a subsample of a panel data set
  • Added function addCovToFormla which adds covariate(s) to a particular formula
  • Removed dependency on qte package
