The col.names=false in the write.csv command does not work as documented.
Attempting to write a vector to a csv file without column headers does not work
as documented. 

The col.names=false feature on the write.table command does however work and it
can thus be coerced into behaving like the write.csv command - which suggests
that there is  a simple error with the write.csv command code.
