vector(mode = "logical", length = 0) as.vector(x, mode = "any") is.vector(x, mode = "any")
vector
produces a vector of the given length and mode. Logical
vector elements are initialized to FALSE
, numeric vector
elements to 0
and character vector elements to ""
.
as.vector
attempts to coerce its argument into a vector of mode
mode
(the default is to coerce to whichever mode is most
convenient). The attributes of x
are removed.
is.vector
returns TRUE
if x
is a vector (of mode
logical, factor, integer, real or character) and FALSE
otherwise.
