Check Arguments of a function.

Description

Check the validity of the arguments in functions.

Usage

validCharacter(
  value1,
  name1 = as.character(substitute(value1)),
  valid.length,
  valid.values = "character",
  refuse.NULL = TRUE,
  refuse.duplicates = FALSE,
  method = NULL,
  addPP = TRUE
)

validClass(
  value1,
  name1 = as.character(substitute(value1)),
  valid.class,
  type = "inherits",
  method = NULL,
  addPP = TRUE
)

validDimension(
  value1,
  value2 = NULL,
  name1 = as.character(substitute(value1)),
  name2 = as.character(substitute(value2)),
  valid.dimension = NULL,
  type = c("NROW", "NCOL"),
  method = NULL,
  addPP = TRUE
)

validInteger(
  value1,
  name1 = as.character(substitute(value1)),
  valid.length,
  min = NULL,
  max = NULL,
  refuse.NA = TRUE,
  refuse.NULL = TRUE,
  refuse.duplicates = FALSE,
  method = NULL,
  addPP = TRUE
)

validLogical(
  value1,
  name1 = as.character(substitute(value1)),
  valid.length,
  refuse.NULL = TRUE,
  refuse.NA = TRUE,
  method = NULL,
  addPP = TRUE
)

validNames(
  value1,
  name1 = as.character(substitute(value1)),
  refuse.NULL = TRUE,
  valid.length = NULL,
  valid.values = NULL,
  required.values = NULL,
  refuse.values = NULL,
  method = NULL,
  addPP = TRUE
)

validNumeric(
  value1,
  name1 = as.character(substitute(value1)),

)

  value1,
  name1 = as.character(substitute(value1)),
  type,
  method = NULL,
  addPP = TRUE,
  extension = NULL,
  check.fsep = FALSE
)

Arguments

`value1`	the value of the (first) argument to be checked
`name1`	the name of the (first) argument.
`valid.length`	the acceptable length(s) for the argument. If `NULL` no test is performed.
`valid.values`	the acceptable value(s) for the argument. If `NULL` no test is performed. Can also be "character" or "character_or_logical".
`refuse.NULL`	should an error be output if value is `NULL`.
`refuse.duplicates`	should an error be output if value contains duplicated values.
`method`	the name of the function using the argument.
`addPP`	add ": " after the name of the function in the error message.
`type`	For `validDimension`: the type of operator used to check the dimensions. For `validPath` either "dir" or "file" to check whether to path points to an existing directory or file.
`value2`	the second value of a second argument whose dimensions should be consistent with the first one
`name2`	the name of the second argument.
`min`	the minimum acceptable value
`max`	the maximum acceptable value
`refuse.NA`	should an error be output if value contains `NA`.
`required.values`	values that must appear in the argument
`refuse.values`	values that must not appear in the argument
`unlist`	[logical] flatten argument before check.
`extension`	filter the files by the type of extension.
`check.fsep`	display a warning when the separator is not correctly specified in
`validClass`	the acceptable classes(s) for the argument.
`validDimension`	the acceptable dimension for the argument. If `NULL` then name2 is used as a reference.
