Dear R-ers, I'm not sure if this is a missing feature, a support request, or stupidity on my part, but nevertheless, its a question. Is it possible to add titles to colorkey legends? As far as I can tell, there is a command to do it for normal "key" legends, but not for "colorkeys". eg it works for a normal key, created through auto.key xyplot(decrease ~ treatment, OrchardSprays, groups = rowpos, type = "a", auto.key = list(space = "right", points = FALSE, lines = TRUE,title="Key title")) but there is no comparable command...

...9;title here', y=unit(0.5, "npc"), rot=90, x=unit(0.88, "npc")) i.e. adding some space between levelplot and colorkey. The x,y positions of the grid.text call need fine-tuning once the plot is close to finalised. Does anyone have a better solution for vertical colorkeys? e.g. can the plot objected be interrogated to work out what the central x,y value is? Thanks, Stephen

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

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

When using a wireframe, I need to move the colorkey from the "right" position (default0 towards the plot. I have also needed to adjust the height and used the code colorkey=list(T,space='right',height=.5) I have looked at documents (within levelplot) but cannot find a way to move the colorkey other than right, left, bottom and top. I do not understand corner interacts with x,

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

I am drawing level plots but I would like to specify the range of the colorkey, I am not having any success figuring this out so any help would be greatly appreciated! Here is an example of what I am trying to do: disp<-1 x <- seq(1, 10,by=1) y <- seq(1,10,by=1) g <- expand.grid(x = x, y = y) g$z <- 1/exp((abs(g$x-5)+abs(g$y-5))*disp) g$z<-g$z/sum(g$z) levelplot(z ~ x * y,

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 ### Three

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, Matt Sundling

Hello, I would like to create a sequence of plots (using a for loop). I read in the FAQ that print() has to be used in order to obtain any output. This works perfectly fine as long as I only consider one function call in the loop, but I would like to add mtext() to the each plot in the loop. Unfortunately, this did not work. Any suggestions? As you can see from the provided example,

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

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

Hi, I use the levelplot function of the lattice library with the option col.regions=gray(200:400/400) in order to get a "color-grid" of 201 different gray colors (actually if you look at the vector, some consecutive colors are the same). In order to make the colors in the colorkey as "smooth/continuous" as possible I use the maximal number which is possible for the

Lattice experts: Can you think of a way to produce a levelplot as below and then add a histogram of the z variable to the top margin of the plot that would sit on top of the color key? x <- seq(pi/4, 5 * pi, length.out = 100) y <- seq(pi/4, 5 * pi, length.out = 100) r <- as.vector(sqrt(outer(x^2, y^2, "+"))) grid <- expand.grid(x=x, y=y) grid$z <- cos(r^2) *

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? cheers Ernst

Hola miembros de la lista, Estoy utilizando la función levelplot del paquete rasterVis para graficar un raster y quiero controlar la altura de la referencia de color (colorkey) del mapa, pero cuando cambio valores en el argumento "height" no parece provocar cambios. Alguna idea de por qué no está funcionando? > cobertura class : RasterLayer dimensions : 780, 1296, 1010880

I decided against creating a new "pvideo" engine -- that just seems way too heavy-handed compared to the ~10 lines of code in disp/nv04.c to deal with the PVIDEO interrupts. Even though

Hi, all. I made the main figure of levelplot upside down by transposing and proper indexing; upper left corner is the biginning of matrix. However, I can't figure out how I can upside down the vertical colorkey right side of the main figure. Any help will be greatly appreciated. Minho

How to add units (e.g. "cm") to the color key of a lattice levelplot? The plots looks fantastic, but it would be nice to indicate somewhere near the end of the color key that the values associated with its colors are in centimeters or some other physical units. The only thing I find is the possibility to specify the labels so that one explicitly includes the units. That leaves
