Hi Blue.Egg,
You can always try barNest:

# first let's get more than one district
bluegg.df$DISTRICT-factor(sample(c(PO,PQ),25,TRUE))
barNest(EGGS.H~DISTRICT+SEX,data=bluegg.df,
 ylab=Mean number of eggs,
 barlabels=list(Overall,c(District PO,District PQ),
 c(Male,Female)),main=Blue.Egg\'s breakdown of eggs,
 col=list(lightgray,c(green,orange),c(pink,lightblue)))

and if you want nested bars, add showall=TRUE. For the t-test:

t.test(EGGS.H~SEX,bluegg.df)

Jim

I need to find out how can I on R, plot the mean egg of EGGS.H according to
the district, or sex.

Also how to compare the eggs of females on year of study x (in t.test)

Thank you!

Are you asking us to do your homework? This is not a homework list.

For the t-test look in any introductory R manual. For the histograms, look
in the lattice library.
