R help - Mar 2011 - Finding the name "vector"

Hello:

Here are some basic class items:
> x <- 1:10
> class(x)
[1] "integer"
> x.mat <- matrix(1:6,nrow=2)
> class(x.mat)
[1] "matrix"
> class(x>3)
[1] "logical"
> test <- function() { plot(1:10) }
> class(test)
[1] "function"
>
Is there something that says "vector", please?  Or does it go to
numeric,
logical, or integer, please?

Thank you.

Consider methods::is if you might ever use attributes:

x<- 1:10
is.vector(x)
# [1] TRUE
comment(x)<- "Mine!"
is.vector(x)
# [1] FALSE
is(x, "vector")
# [1] TRUE
