R Documentation

Is given argument an atomic vector or factor of length 1?

Description

More specific functions for scalars of a given type exist, too.

Usage

isScalarValue(x, na.ok = TRUE, null.ok = FALSE, type = "atomic")

isScalarLogical(x, na.ok = TRUE, null.ok = FALSE)

isScalarNumeric(x, na.ok = TRUE, null.ok = FALSE)

isScalarInteger(x, na.ok = TRUE, null.ok = FALSE)

isScalarComplex(x, na.ok = TRUE, null.ok = FALSE)

isScalarCharacter(x, na.ok = TRUE, null.ok = FALSE)

isScalarFactor(x, na.ok = TRUE, null.ok = FALSE)

Arguments

`x`	[any] Argument.
`na.ok`	[`logical(1)`] Is `NA` considered a scalar? Default is `TRUE`.
`null.ok`	[`logical(1)`] Is `NULL` considered a scalar? Default is `FALSE`.
`type`	[`character(1)`] Allows to restrict to specific type, e.g., “numeric”? But instead of this argument you might want to consider using `isScalar<Type>`. Default is “atomic”, so no special restriction.
