Hi Lars,
in a 3-dim array you have 3 axes, day x, y and z (which I named
xNo/xYes, yNo/yYes and zSmall/zBig)
to assign directly the labels use :
> tab <- array(1:8, c(2, 2, 2),dimnames= list(c("xNo","xYes"),
c("yNo","yYes"),c("zBig","zSmall")))
> tab
, , zBig
yNo yYes
xNo 1 3
xYes 2 4
, , zSmall
yNo yYes
xNo 5 7
xYes 6 8
If you wanted to have an array allowing to capture xNo/xYes vs yNo/yYes
AND zBig","zSmall" vs aaBig","aaSmall" you need to go one dimension
higher .. but I'm not sure if this is really what you wanted.
Hope this helps,
Wolfgang
