[R] barchart in lattice

[Dieter Menne]

Bernd,

for counts use histogram instead of barchart, and leave the left side of the
formula empty.

library(lattice)
meta<-read.table("meta.txt",header=T)
histogram(~daten.COUNTRY|daten.STATUS,data=meta)

Check "scales" in xyplot (it's also valid for histogram) so you get the
names of the
countries as vertical x-labels instead of the numbers.

I have two factors 'country' and 'status' which I would like to plot via
barchart (lattice). 'status' consist of three different levels and should be
the grouping variable, i.e. there should be drawn three different panels and
within each panel a barchart of 'country'.

barchart(daten$COUNTRY|daten$STATUS),
barchart(table(daten$COUNTRY)|table(daten$STATUS)),
