Hi,
If you go to the frame on www.r-project.org -> documentation -> publication and search for "blue book" "green book" you will find that this refers to two books : /"The New S Language" //"Programming with Data" respectively / Mass refers to "/Modern Applied Statistics with S"/ /E

I depend on this all the time, so I also checked some references. In theuses
Blue book the documentation for the functions unique and duplicated is
combined and implies the above. In MASS 4th Ed, the page referred to by
the index entry for 'unique' (p48, #9 in my copy) states that 'unique'
removes duplicates as identified by 'duplicated', which implies that the
order of retained elements is not changed. The Green book has no index
entry for 'unique'. In S-plus the implementation of unique.default(x)
x[!duplicated(x)].
So what is the "Blue book", the "Green book", and MASS 4th Ed?
