Anti-join two data frames (base R)

Base-R replacement for dplyr::anti_join(x, y, by). Builds a pasted composite key from by (treating NA as the literal string "NA", matching dplyr's NA-as-equal join semantics) and keeps rows of x whose key isn't present in y.

Usage

anti_join_base(x, y, by)

Arguments

x

a data.frame or tibble

y

a data.frame or tibble

by

character vector of shared key column(s)

Value

rows of x with no matching by-key combination in y, keeping only x's columns
