How to label a "vector"

Use dimnames:

dimnames(Z) <- list(c("X1", "X2"), c("X1", "X2", "X3"))
Hi,

I have an object, Z:

typeof(Z)
[1] "list"

It looks like:

    [,1] [,2] [,3]
[1,]  1    1    1
[2,]  1    1    1

How can it label the Rows and Columns with Text? so that it looks like:

    Y1  Y2  Y3
X1   1    1    1
X2   1    1    1

Thanks,
cruz
