I am trying to get segplot honor the groups parameter like barchart does. The
below give an incorrect display for segplot.
Any help?
Dieter
# seqplot bar coloring
library(latticeExtra)
d = data.frame(acid=letters[1:10],lwr=rnorm(10),
essential=rep(c(TRUE,FALSE),each=5))
d$upr = d$lwr+1
# Works as expected
barchart(acid~lwr,data=d,
groups=essential,
par.settings=list(plot.polygon=list(col=c("red","blue"))))
# looks like groups not used
segplot(acid~lwr+upr,data=d,
groups=essential,
par.settings=list(plot.polygon=list(col=c("red","blue"))))
