similar to: Titles on lattice 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 R is not yet

Dear R gurus, I have got stuck on how to customise the colorkey generated by levelplot and contourplot, in the lattice package. This best illustrated by an example: library(lattice) levelplot(volcano^20/1e45,at=c(0,0.001,0.01,0.1,1,10)) The reason for raising the volcano dataset to the 20th power is to create a dataset with a large vertical exaggeration - this is similar in nature to the data

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),

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

Hi All, Can anyone please help me with getting a "single title" and "legend" for both the plots in the following R code. I'll eventually be using .wmf file. # R code: library(lattice) p1 <- xyplot(decrease ~ treatment, OrchardSprays, groups = rowpos, type = "a", main="Same title / legend", auto.key = list(space = "right",

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'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

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,

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) *

Here is an example: The legends (mainly the factor level names) are cut off on the right. Somehow the internal calculation which computes horizontal space for the legend is not flexible enough. ## Call a new graphics window {with default par()s !}: get(getOption("device"))() par(mfrow = c(2,2)) ## part of example(interaction.plot) _improved_ using with() : data(OrchardSprays)

Dear R users- Do the lattice/latticeExtra packages support multiple tileplots with unique colorkeys? I am trying to create a visualization of the encounter rate of certain stocks of salmon across two years. The issue I am having is that some stocks are encountered at much higher rates than others.the high encounter rate for one stock washes out the patterns I'm hoping to visualize across the

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

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

Hi All, I'm trying to draw boxplots. I'm having a hard time to get "ticks labels" on multiple panels using 'alternating' option. # R Code: # May not be the best example, please just look into 'scales' option library(lattice) data(OrchardSprays) dta <- subset(OrchardSprays, OrchardSprays$rowpos %in% c(1,2,3)) # Original # This works fine, as you can see

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

I?m entirely stumped on this particular issue and really hoping someone has some advice for me. I am running a covariant model in lm I would like to give the standard errors or the confidence intervals for the fitted lines. I?ve been using the dataset OrangeSprays where I want lines for each level of treatment over the covariant ?colpos?. I?ve been able to calculate intercepts and slopes for

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

hello everybody, I want to print two plots in one png file, I tried several options but i didn't succeed the first plot (bwplot) print to the defined position, but the second (ggplot) doesn't Any idea? Thanks a lot Christophe # Example: #------------------------------------- library(ggplot2) library(lattice) library(grid) one <- bwplot(decrease ~ treatment, OrchardSprays, groups

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
