Details

This is a simple useful way of defining arrays to be used for collection of results. The point is that everything is defined from the named list, so in the process of defining what you want to collect, there is only one place in the program to edit. It's just a wrapper for array. ZArray is just a wrapper for NArray with a different default.

Examples

# NOT RUN {
ftable(
NArray( list(Aye = c("Yes", "Si", "Oui"),
             Bee = c("Hum", "Buzz"),
             Sea = c("White", "Black", "Red", "Dead") ) ) )
# }
