[R] basic statistics to csv

[Adaikalavan Ramasamy]

It would be useful to have a simplified version of the 'nsu' object.

I am guessing it is a list of some sort (e.g. mean is single value, 
quantiles here returns 5 numbers) and not a matrix or dataframe (i.e. 
regular array). So you can have several choices here:

1) print nsu to a file. e.g. cat(nsu, file="lala", append=T) or using 
the sequence sink(file="lala"); print(nsu); sink()

2) compile the nsu objects into a list (if generating nsu takes time, 
you can save each nsu and then have a script to read them all into a 
list). Then extract the means across the elements in the list (e.g. 
sapply) and compile into a regular array before using csv.

Regards, Adai
