Multiple lattice levelplots from matrices
Dear R-users,
My goal is to construct a levelplot (from the lattice package) with 4 or more individual plots sharing the same colorkey. While this appears to be relatively simple using functions, I haven't been able to find a solution using data matrices. An example of a working levelplot with just one matrix:
d <- replicate(10,rnorm(10))
levelplot(d)
I have found partial solutions using

How to select the scale parameter for Gabor transform (Rwave)?
Dear list,
I am trying to choose the scale parameter for the cgt transform but I don't
know how to do it. In time I would like to be able to separate points 30
samples apart, and in frequency I would like to separate bands 0.04 Hz
apart. I tried the two approaches described below and they gave me
different results. I would appreciate advise on how to do this.

Layout within levelplot from the lattice package
Hi,
I'm a novice with levelplot and need some assistance! Basically, I want a window
which contains 6 levelplots of equal size presented in 3 columns and 2 rows.
I've tried to approach it two ways. The first way leads to this question:
Is there any way to concatenate levelplots from a factor vertically as opposed
to horizontally? I'd like to pair the levelplots by factor.2 on

wireframe, axis label-axis separation, xlab rotation
Greetings,
A couple of questions:
1.
I am using wireframe. It prints 3d plots nicely on screen, but when I use a
postscript device the z-axis label merges with the z-axis. Is there any option
to control their separation?
2.
Again, using wireframe, I rotate the whole plot using the screen parameter.
However, the x- and y-axis labels (xlab and ylab) remain horizontal. How could
I rotate them?

helps on levelplot
I'm a new user of levelplot, and are not familiar with the terminology
very well. Is the bar alongside the levelplot indicating color or shade
call "colorkey"? I have to adjust the size of its label, but couldn't
make it so far. This is how I did:
levelplot(z~x*y, grid, at=seq(0,1,by=0.1),
colorkey=list(labels=list(cex=2)))
But I got error message "Error in

Different scales for keys in lattice levelplots
Can anyone tell me how to obtain a custom scale for
the colorkey in each levelplot of a lattice? I am using
lattice and levelplot to plot z = f(x, y) for multiple z
variables. x and y values are the same across plots, but
units for z are different and therefore I need to create
a custom scale for each plot's key. It follows that I need
to place each plot's key inside that plot's

controlling panel.width and panel.height in viewports
Dear all,
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

lattice multiple plots per page
Dear R-sters,
I was wondering if anyone has encountered the following issues. I've
figured out how to get multiple levelplots [library(lattice)] on a single
plot. However, when I add text (adding axis labels for the entire four
panel plot) the text is missing when I insert the *.eps file I've created
into my LaTeX document (via MikTeX-WinEdt). And, I've just upgraded to R

multipanel display of levelplots?
I cannot achieve a multipanel display of several levelplots. Here is
part of my code.
At first, create the layout:
push.viewport(viewport(layout=grid.layout(1, 2)))
Then for the left panel:
push.viewport(viewport(layout.pos.col=1,layout.pos.row=1))
push.viewport(viewport(width=0.6, height=0.6))
levelplot(z~x*y, grid)
pop.viewport()
Similar code for the right panel.
However, there is always

Fwd: Re: How to create following chart for visualizing multivariate time series
Thanks David, It is working. Holtman's also gave me a solution but, I wanted to have a color pallet for description of colors, that was not in his solution.
However I need one small modification. If I want to plot only lower diagonal elements of 'dat' then how should I proceed? What I want is, to visualize only lower diagonal elements and having the color pallet on them only. Also

aligning axis labels in a colorkey from levelplot
R does a great job with the fine details regarding plots. e.g in the
following:
library(lattice)
y <- -4:4/10
xyplot(y~1, las=1)
the y axis is labelled with numbers -0.4, -0.2, 0.0, 0.2, 0.4 with the
numbers aligned on the decimal point.
How do I get the same behaviour in the colorkey of a levelplot? e.g.
levelplot(matrix(y,3,3))
the numbers in the colorkey seem left-aligned, and

Adding title to colorkey
A recent paper on visualisation (in Neuron, a leading neuroscience
journal) surveyed how well previous articles in this journal labelled their
graphs (e.g. axis labelling and describing their error bars). Of
particular interest is that (only) 40% of plots labelled what their
colorkey was showing (variable and units).
The paper is at http://dx.doi.org/10.1016/j.neuron.2012.05.001

lattice package plots
I am using the lattice packge for its levelplot and contourplot. Is it
possible to adjust the line thickness of the 'box' and tickmarks in these
plots?
Thanks for the attention,

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:

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

Can levelplot colorkeys display a logarithmic scale evenly?
I'm using the {lattice} "levelplot" function to make a (more or less) 2-d
histogram, and for the most part it's working fine with my data. However, I
can't get the color key to do what I need. I can give it labels and custom
cutoffs, but my cutoff lines (and hence my labels) aren't evenly spaced, instead
they're more-or-less logarithmic, starting at

add single contour line to levelplot

I want to add a single contour line to a levelplot but can't figure out
how to do it 'on-the-fly'. When I include the last line in the code below,

legend problems in lattice
Hi!
Im sorry to bother you but I cant fix this.
I use the lattice function levelplot and I want the colorkey at the
bottom, how do I get it there? I have tried changing colorkey.space and
changing in legend but I cant get it right, plz help
btw I'd like to speceify strings to appear at the tick marks and also
there I fail any thoughts?

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,
levelplot(z, contour=T, labels=T, cuts=10, region=T,...

at=seq(0,2000,length=20),
