color points by qvalues in regression plot

[tdelhomme]

for example take colors on a rainbow, don't forget to show the corresponding palette (same as for benchmarking? i.e. stopped at 100)

par(mfrow=c(1,2))
vect=sample(1:10,10)
plot(vect,vect,col=rainbow(length(vect)),pch=19)
plot(vect,vect,col=rainbow(length(vect))[match(vect,sort(vect))],pch=19)

[tdelhomme]

add at the same time the sample name of outliers in the plot, near their points.
