[R] Listing function

[Michael T. Mader]

Lst <- list()
Lst[[1]] <- list(name="Fred", wife="Mary", no.children=3, 
cild.ages=c(4,7,9))
Lst[[2]] <- list(name="Barney", wife="Liz", no.children=2, cild.ages=c(3,5))

I.e. a list of lists

Program testing can be quite effective for showing the presence of bugs, 
but is hopelessly inadequate for showing their absence.
