Dear ALL,
I have a dataset contains 2 variables: mate (mating groups) and ratio (ratio of
number of mothers and fathers). And mate is an identifer which consists three
components: year, flock (flk), and tag.
I am using command "barchart" under package "lattice" to generate plots of
ratio against mate divided by each flock (See attachment). I want to put flock names onto the
corresponding plots, but don't know how.
Cheers, Sid
load("ratiodata.Rdata")
attach(ratiodata)
in general it is a bad idea to use attach, use the data= parameter if
available.
head(ratiodata)
mate ratio1 2007.102.A 21.285712 2007.102.B 68.200003 2007.102.C

library("lattice")
ratiodata$flk=read.table(text=as.character(ratiodata$mate),sep=".")[,2]
So what did this give you for flk?
barchart(ratiodata$ratio~ratiodata$mate|ratiodata$flk)
This could be
barchart(ratio ~ mate | flk, data = ratiodata)
which is much easier to read.
So what did it label the panels with?
