Just ***WHAT*** do you think the ``c( )'' is doing for you in
the construction ``c('phenotype')'' etc. ???

Such complete misunderstanding of what the c() does or is useful
for exasperates me, and is unfortunately very wide spread.  If people
are going to use R, why don't they learn the basic syntax?
