Have you tried 'str(test)'? This tells me it is "Formal class
'kpssstat' [package "uroot"] with 5 slots". I can access the slot
'ltrunc' and the component 'rank' of the 'lmkpss' slot as follows:

[1] 7

[1] 2
Hope this helps.

p.s. I'm not familiar with the 'KPSS.test'. I used
RSiteSearch("KPSS.test", "functions") to find it was in package 'uroot'.
