R experts,
Is there anyway to reorder inside each group? In the following example, the
bar of year 1932 is always plotted before the bar of year 1931, may I change
the order inside each groups of bars?
Do you mean a different order in different panels? That seems to
me to defeat the purpose of panels. I can't think of an easy way
to do that.
library(lattice)
barchart(yield ~ variety | site,data=barley, groups = year, layout =
c(1,6),auto.key = list(points = FALSE, rectangles = TRUE, space =
"right"),ylab = "Barley Yield (bushels/acre)",scales = list(x = list(rot =
45)))
Another questions is: may I specify the various ranges of y axis for each
row of the panels? In the example of above, how can I change the y range of
"Waseca" panel to (40,70) from the default (0,80)? Please notice I don't
want to set arguement "scales = list(y=list(relation='free'))", for the
automatic various setting of ranges for different panels isn't good enough
for me. Basically I'd like to manually control y ranges.
You can use scales() with
y=list(relation='free', ylim=mylist)
where mylist is a list of ylims:
mylim <- list(c(0,30), c(40,80), ....)
