forcing levelplot to use relative cuts (ie cuts for each panel)
Dear guRus,
I'm having trouble producing a levelplot with relative cuts for each
panel (my data has large differences in scales, so I want to use
quantiles for each panel).
My attempts to change the 'at' argument in panel.levelplot function
have not met with success.
Below is a toy example.
xy <- expand.grid(x = 1:3, y = 1:3)
aaa <- rbind(cbind(xy, z = 1:9, site =

Lattice: use levelplot as panel for wireframe
Hi,
I want to draw a figure similar to http://dsarkar.fhcrc.org/lattice/book/images/Figure_13_07_stdBW.png
from http://lmdvr.r-forge.r-project.org/figures/figures.html (figure
13.7) . However instead of using a contour plot as a panel for the
wireframe I want to use a levelplot. Can somebody help me with this?
Thanks in advance for any help,
Kind regards,

contour lines for levelplot
Hi,
I would like to add contour lines to a (trellis/lattice-) levelplot.
Sure, there is the "contour=TRUE" argument, but this uses
"cuts=..." (which is usually chosen very high for my plots. I guess
cuts=99 is the best you can do (?)) for plotting the contour lines.
Furthermore, I do not like the numbering of the contour lines this
way. Therefore, I tried to add a

levelplot behaviour when "at" cuts the z range
Consider the following examples:
library(lattice)
x = c(1,1,2,2)
y = c(1,2,1,2)
z = 1:4
levelplot(z~x+y,at=c(.5, 1.5, 2.5, 3.5, 4.5)) # correct
levelplot(z~x+y,at=c(.5, 1.5, 2.5)) # ?
The second plot is clearly incorrect. However, I don't know
what correct behaviour is: ignore everything above 2.5 and
issue a warning? Reject at values that do not cover the
data range, and issue an

[R] proposal: lattice/levelplot: panel.catlevelplot
I suggest to add a panel function to levelplot (or perhaps
to an other 3d lattice function) which is able to translate
the z values into the size of the rectangles.
It could be used to display categorical data.
I append the proposed code and two examples:
- panel.catlevelplot()
- example1.catlevelplot.esoph()
- example2.catlevelplot.esoph()

overlaying a contour line in a levelplot
Hello there,
I am creating a series of images using levelplot but I also want to
overlay a contour for a particular value as reference. Here is the
levelplot command for the image:

NULL,col.regions=heat.colors(100)[100:1]),split=c(1,1,1,1),more=T)

decrease amount of ticks on y axis in lattice levelplot
Hi all,
How can I decrease the number of ticks on the y-axis in a lattice
levelplot()? I have as many ticks displayed on the y-axis as I have
columns of data (1000 columns), how can I decrease this amount of ticks,
while still properly displaying all the data?
Note that I get my data from a matrix object, in which the z-values of
the levelplot are the actual values in the matrix, whereas the

levelplot colorkey
Dear R'ers,
I've scanned available documentation and the web, but I can't seem to
figure out where I've gone wrong in adding numbers to scale the colorkey in
levelplot (Lattice package). For example,

colorkey=list(T, space="bottom",
at=seq(0,2000,length=20),

thicker axis in levelplot
Dear R-help community,
I need to find out how to make the black axis line around my plot thicker in
levelplot, I cannot find the correct command in ?levelplot or ?par - or if it is
there I cannot get it to work - any help would be more that appreciated!
Here's an example script - I would want the code for making the axis bordering
the plot thicker:

add single contour line to levelplot

lattice levelplot axis + custom annotations
How would I set the "scales" property of a lattice levelplot, so that
I can add specific annotations at specific positions?
For example, I have a 200 x 1000 element levelplot. Along the y-axis
(along the 1000-element axis) I would like to add annotations on the
left side of the levelplot at elements 120, 300, 500, and 805, which
represent clusters of interest.
Currently I have

How to change color the default in levelplot() ?
Dear R communities
May I seek your advices on how to change color the default in levelplot(), e.g. from the default of pink and light blue, to e.g. red and green ?
The levelplot function has 1 of the arguments being panel (which is actually panel.levelplot), but I am not sure where the commands to alter the color.
For example, I type:

levelplot and source() problems
I have been using levelplot but have had trouble calling it inside
functions - something seems to go wrong when it's not called directly from
the R command prompt. Simplest reproducible example:

> levelplot(matrix(1:4,2,2))
- This gives a nice plot in soothing pastel colors.

controlling panel.width and panel.height in viewports

I'm trying to get a series of lattice levelplots to appear in
viewports in a particular way but struggling to exert fine control
over their appearence. There are two conditions: (a) I only want the
levelplot to appear (I don't want axes, colour key, etc) in the
viewport and (b) I want the levelplot to expand to the maximum
allowable space in the viewport while observing
