Check if Any of Given Vector Types

Wrapper around is.vector that allows the mode argument to accept a character vector of multiple specific types. TRUE is returned if the given object is any of the given types.

Usage

isVector(x, mode = "any")

Arguments

x: an R object.
mode: character string (or chr vector) naming an atomic mode or "list" or "expression" or "any". When using "any", it must be given on its own.

Value

TRUE or FALSE.

Details

See is.vector for full details and for the types that can be checked with mode.

Examples

x <- c(a = 1, b = 2)
isVector(x) # default `mode` is "any"
#> [1] TRUE

# "any" can't be given with other types.
try(isVector(x, mode = c("numeric", "any")))
#> Error in isVector(x, mode = c("numeric", "any")) : 
#>   In argument ‘mode’: 'any' cannot be given with other types.

# `TRUE` is returned if *any* of the types are matched.
isVector(x, mode = c("character", "list", "logical", "numeric"))
#> [1] TRUE
isVector(x, mode = c("character", "list", "logical"))
#> [1] FALSE
