Remove duplicates

Description

When removing duplicates, users can specify a set columns to consider with the target_columns argument.

Usage

remove_duplicates(data, target_columns = NULL)

Arguments

`data`	The input `<data.frame>` or `<linelist>`.
`target_columns`	A `<vector>` of column names to use when looking for duplicates. When the input data is a `linelist` object, this parameter can be set to `linelist_tags` if you wish to look for duplicates on tagged columns only. Default is `NULL`.

Value

The input data <data.frame> or <linelist> without the duplicated rows identified from all or the specified columns.

Examples

no_dups <- remove_duplicates(
  data = readRDS(
    system.file("extdata", "test_linelist.RDS", package = "cleanepi")
  ),
  target_columns = "linelist_tags"
)
