A symbolic vector is represented by VecBasic S4 class. Vector and V are constructors of VecBasic.

Vector(x, ...)

V(...)

Arguments

x, ...

R objects.

Value

A VecBasic.

Details

There are some differences between Vector and V.

  • For double values, V will check whether they are whole number, and convert them to integer if so. Vector will not.

  • V does not accept "non-scalar" arguments, like Vector(c(1,2,3)).

Examples

a <- S("a") b <- S("b") Vector(a, b, a + b, 42L)
#> VecBasic of length 4 #> V( a, b, a + b, 42 )
Vector(list(a, b, 42L))
#> VecBasic of length 3 #> V( a, b, 42 )
Vector(1,2,a)
#> VecBasic of length 3 #> V( 1.0, 2.0, a )
V(1,2,a)
#> VecBasic of length 3 #> V( 1, 2, a )
