lattice: showing panels for factor levels with no values
How to show panels for factor levels of conditioning variables
which do have no values?
E.g. there are panels for "Grand Rapids" when they have values:
data( barley )
with( barley, dotplot(variety ~ yield | year * site, layout=c(6,2) ) )
There are no panels for "Grand Rapids"
when there are no values for "Grand Rapids":

lattice: cumsum and xyplot
I want to display cumulative summary functions with lattice.
First I tried to get cumulated data:
library(lattice)
data(barley)
d.cum <- with( barley, by( yield, INDICES=list(site=site,year=year), FUN=cumsum ) )
I got a list of vectors.
I tried to get a dataframe which I could use in xyplot.
But neither of the following functions led to the goal:

dotplot (lattice) with panel.segments and groups
Hi,
The following produces almost exactly what I needed. The problems are
that the 'panel.dotplot' call (commented) generates the error 'Error in
NextMethod("[") : argument "subscripts" is missing, with no default'. The
other problem is that the colors alternate between the levels of the 'site'
variable, rather than 'year'.

Does this not do what you want ... ?

[FORGED] Extracting specified pages from a lattice ("trellis") object.
Hi
I think the subsetting works by giving you the panels for the
corresponding levels of the conditioning variable(s). Note that, if
there is more than one conditioning variable, you will need more than
one subsetting index.
For example, taking this plot with two conditioning variables and 12
panels in total ...
dotplot(variety ~ yield | year * site, data=barley)

Adding ranks to a repeatedly ragged array
How can I add an extra column containing the rank
to a ragged array indexed by more than one grouping
factors?
E.g. with the barley dataset:
How can I to add an additional column ``rank''
containing the rank of the ``yield'' of
the different varieties in relation to the indices
``year'' and ``site'' to the barley dataframe?

(PR#6005) Re: [R] lattice: levelplot: error: min not meaningful
Actually, this is supposed to work (and is given as an example in my DSC-2003
paper), and at some point, did. It seems this was broken as a consequence of
a careless change in panel.levelplot. The first 5 lines should have been

x <- as.numeric(x[subscripts])
y <- as.numeric(y[subscripts])

converting lists got by tapply to dataframes
I have two lists:
xa <- list( X=c(1,2,3), Y=c(4,5,6), Z=c(7,8,9) )
xb <- with( barley, tapply( X=seq(1:nrow(barley)), INDEX=site
, FUN=function(z)yield[z]))
I can convert xa to a dataframe easily with:
as.data.frame(xa)
But if i try the same with xb I get:
as.data.frame(xb)
Error in as.data.frame.default(xb) :
can't coerce array into a data.frame

bwplot() {lattice}
Hi All,
I'm trying to plot boxplot graph. I tried barchart with "groups=" option and
it worked fine. But when I try to generate same kind of graph using
bwplot(), "groups=" option doesn't seem to work. Though this works,

I'm thinking why "groups=" doesn't work in this case, can anyone help

panel function with barchart (lattice)
Folks at R help,
I can't quite get the panel function to work the way I
want within barchart.
I guess I'm still not understanding how to piece
together multiple panel
arguments, especially when "groups" is specified.
Example: I want to be able to add the value of "yield"
to each section of
each bar in this graph:

strip.custom() with more than one conditioning variable
Suppose I wanted to plot the barley data like this:
dotplot(variety ~ yield | year+ site, barley,
strip = strip.custom(style = 4))
The factor levels are far too long for that to be useful. I can
overcome that problem if I shorten the levels like this:
dotplot(variety ~ yield | year + site, barley,
strip = strip.custom(style = 4,

color of error bars in Dotplot (Hmisc)
Hello!
In a grouped Dotplot, is there any way to set the color of error bars
to be the same as the corresponding symbols?
Example data:

data(barley)

I experimented with changing trellis settings of plot.line (as

Lattice : factor levels in the margins
Hello !
I'm struggling again against lattice graprhics. ;) I'm trying to produce
a conditionnal xyplot with two conditionning factors (let's say A and
B). I want the levels of those factors (A1, A2, etc) to show in the
margins of the lattice plot, not in the strips between the panels.
