Hi all, I'm trying to do an example in Deepayan Sarkar's Lattice book. It involves making a barchart based on the Titanic dataset. I can get the barchart to plot fine; however, when I try to edit panel.grid, I get an error:
titan<-barchart(Class ~ Freq | Age + Sex, data =
as.data.frame(Titanic), groups=Survived, stack=TRUE, layout=c(4,1), auto.key=list(title="Survived", columns=2), scales=list(x="free"))
titan <--- this plot is fine
update(titan, panel = function(...) { panel.barchart(...)}) <---
same thing; also fine
update(titan, panel = function(...) { panel.grid(h = 0,v = -1)
panel.barchart(...)})
Scanning that line makes me wonder if you are forgetting to separate
the individual panel calls with the appropriate separator (";").
Error: syntax error Any advice? I'm using R 2.8.1 on OS X Leopard if it helps.
My advice would be to spend a bit more time articulating your goals.
