Description

DEPRECATED: Use dplyr to emulate Stata merges.

Usage

merge_stata(
  x,
  y,
  multi = c("1:1", "1:m", "m:1", "1:1 _n"),
  by = NULL,
  keep = "inner",
  keepusing = NULL,
  ...
)

Arguments

x	A dataframe to merge ('master' in Stata)
y	A dataframe to merge ('using' in Stata)
multi	What multiple matches are allowed? One of "1:1", "1:m", "m:1", or "1:1 _n". Note that m:m matches aren't allowed because they're ill-defined. You can use standard dplyr joins if you instead want the cartesian product (equivalent to Stata's joinby).
by	Variables to join by (as strings)
keep	Observations to keep. Can be specified with Stata words (1, 2, 3, "master", "using", "match") or SQL words ("left", "right", "full", "semi").
keepusing	Variables from the y ('using') dataset to keep.
...	Other arguments passed onto the dplyr *_join function.
