Subject: [R] Need help using lattice
I have a dataframe comprising a vector of E. coli concentrations, a vector of
months when the samples were taken, and a vector of sampled sites. I?d
like to produce a lattice with sites along the horizontal axis, and months on
the vertical. Each site-month box would then contain concentrations ranging
along its x axis.
I think this would use dotchart (or possibly stripchart) in the lattice. I?ve
been reading the lattice and xyplot documents and I?m overwhelmed. I?d
appreciate help in how to write the call.
David
