Read Mapping

Description

Read mapping table.

Usage

read_mapping(
  file,
  mode = "table",
  sep = ";",
  self.match = FALSE,
  include.lowercase = FALSE,
  ignore.empty = FALSE,
  sort = FALSE,
  verbose = FALSE,
  remove.ambiguous = TRUE,
  lowercase.only = FALSE,
  from = "synonyme",
  to = "name",
  fast = FALSE,
  encoding = "UTF-8",
  trim = FALSE,
  empty.is.na = FALSE
)

Arguments

`file`	Input file
`mode`	The input file type: "list", "vector" or "table"; see details.
`sep`	Separator mark.
`self.match`	Include self matches
`include.lowercase`	Include lowercase
`ignore.empty`	Ignore the empty cases
`sort`	Sort synonymes
`verbose`	verbose
`remove.ambiguous`	Remove ambiguous terms.
`lowercase.only`	All synonymes considered in lowercase only
`from`	field that will be replaced
`to`	field that contains the final names
`fast`	Use the fast method fread (sensitive to problems in table format)
`encoding`	Character encoding (needed in Windows environment)
`trim`	trim empty spaces from the beginning and end of the strings
`empty.is.na`	Interpret empty conversions as NA. By default this is FALSE.

Details

If mode = "list", each row of the input file corresponds to a unique entry with potentially multiple name variants, separated by semicolon. The first element gives the selected version of the name, the subsequent elements list synonymes that will be mapped to the selected version. If mode = "table", the file has two columns where each row corresponds to a unique entry and has the selected name and a single alternative name.
