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:
x<- seq(pi/4, 5*pi,length=100)

Overlaying a single contour from a new data array in levelplot
Dear R-Help community,
I am trying to overlay a single contour line over a correlation plot using
levelplot in the lattice package. These are the two arrays:
1) a correlation plot over Africa - so each grid square is a different colour
dependent on correlation - this is in an array: result_cor with dim[465,465]
2) a single contour line from a ***different data source*** - this is from data

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

How to color a region in a contour plot with the contour being the boundary?
Dear expeRts,
I would like to color a certain region in a levelplot. The region for z <= 0.02 should have a dark gray color. Below is a minimal example. It almost does what I want, but The region between z=0.02 and z=1 is also colored in dark gray (instead of just the region for z <= 0.02).
How can I solve this?
Cheers,
Marius

add single contour line to levelplot
Hello,
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,
I get the following error:
Error in NextMethod("[") : Argument "subscripts" is missing, with no default
Any tips on how to fix this are greatly appreciated!

don't draw legend in filled.contour plot
I hope this will be an easy question to resolve, but I haven't been able to
find a way to hide a legend in a filled.contour plot. I've looked at the
filled.contour help file and Googled, but to no avail so far.
I'd appreciate any solutions to the problem.
Thanks,

upside down image/data
Dear R-community,
I am looking for some simple advice - I have a matrix (therefore 2 dimensional)
of global temperature.
Having read R-help I think that when I ask R to image() or levelplot() my matrix
will it actually appear upside down - I think I therefore need to use the line:
> levelplot(temperature.matrix[,ncol(output.temp):1], ........)
to get it looking like it was on the globe due

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

How to use filled.contour(x,y,z) data for levelplot(z)?
Dear all,
We used the following function to create a spatial plot of a raster image:

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,...

gray background in png
Hi all,
I'm having a problem creating png images with trellis.device. I would
like to create many plots with a white background using a sequence
number in the file argument (i.e. "%02d"). The first plot is as expected
with a white background. However, the second and all subsequent plots
have a gray background. I would like all plots to have a white (or
transparent)

filled.contour colorbar without black color separators?
Dear list members,
I have been using filled.contour in order to plot EEG data. For the colors, I used a conventional ramp from blue to red (blue - green - yellow - red), and 100 color levels to make the plot looking smooth:
(...) color.palette = colorRampPalette(c('blue','green', 'yellow','red'), space='rgb'), nlevels = 100 (...)

Filled Contour.
Hi.
I'm a big user of level plots. Because filled.contour() didn't do exactly
what I wanted, I hacked at it a bit to add these options:
(*) Even spacing in the key, even if the contours are not evenly spaced.
(*) Horizontal key
(*) options to not use layout() and to plot only the level plot _or_
only the key. This means you can use layout yourself to (e.g.)
have several

3 levelplots and 1 colorbar
I want to create a simple plot containing three levelplots with one colorbar.
I used the "Three levelplots" code below, but the third levelplot is drawn
smaller than the first two. However, if I try the "Two levelplots" code below
it works well. Can anybody tell me how could I draw three levelplots (of the
same size) with one colorbar.
Thanks in advance, Joaquin

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?

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

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

positioning of color key in levelplot
Is there a way of positioning the color key in levelplot when the axes are on a categorical (rather than numerical) scale? I've put some sample code below. I need to add a secondary y axis to the right side of my plot but then the labels interfere with the color key (which is currently on the right side). Is there a way to shift the color key over a bit more to the right? I've tried
