lattice: adding text between grouped panels?
How one can add a text (e.g. the labels of an axis)
in a space between grouped panels which was created
by using the argument ``between''?
Example:
data(barley)
dotplot(variety ~ yield | site * year, data=barley,
between=list(x=c( 0, 0, 6 ))
How to add labels for the y axis in the space in the middle?
Thanks

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":

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,

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?
I achieved to calculate the ranks with:

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

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'.

change plotting symbol for groups in trellis graph
Hi,
how can I change the plotting symbol for the groups in a trellis panel dotplot.
My graph is similar to:

key = simpleKey(levels(barley$year), space = "right"),
xlab = "Barley Yield (bushels/acre) ",

[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)
... this produces three

dotplot points color
Dear list,
is it possible to change the background color of dotplot's points? I tried
in many ways but unsuccessfully
Thanks in advance

Equivalent of box() in grid graphics
Paul Murell's article "What's in a Name" in The R Journal Vol 4/2
gives an interesting example of editing a stacked barplot of the barley
data. Using the method described in that article, it's easy to do
something along the lines of
grid.edit("plot_01.border.strip.1",
grep=TRUE, global=TRUE,
gp=gpar(col = "red"))

Dotplot (package Hmisc) with groups: colours and symbols
Hello all,
This question concerns the function Dotplot from the Hmisc package.
My aim is to compare values between groups in each panel of the
Dotplot, with the values of different groups clearly distinguishable
by different symbols. All lines and symbols should be coloured in
black.
Before adding the panel function to the Dotplot, the groups behaved as
desired and were marked by different

RSQLite problems
Hi, I'm experimenting with using (R)SQLite to do data management. Here are
two little problems that I've encountered:
1. The presence of ',' in string values causes trouble since ',' is also the
delimiter used in the SQL statement.
2. A newline '\n' line attached to the last string value of each row.
Some examples:

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:
require(lattice)
require(Hmisc)
data(barley)
Dotplot(variety~Cbind(yield, yield+2, yield-2)|year, groups=site,
data=barley)
I experimented with changing trellis settings of plot.line (as
mentioned in the Hmisc documentation) as well as col.line settings in
