similar to: How do I upside down colorkey of levelplot?

Dear R users, I am tryting to save an 3d array to a matlab file like the following. A <- array(1:24, c(2,3,4)) writeMat(filename, A=A) But if I load the mat file from Matlab, it is not 3d matrix anymore. Does anyone know how I can preserve the 3d structure? Any help will be greatly appreciated. Minho Chae [[alternative HTML version deleted]]

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),

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) *

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

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

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

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

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

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,

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,

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

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,

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

Dear R-users, I'd like to place an xyplot() at the top of a page and a levelplot() at the bottom of the same page, and have the x-axes be the same. I've come close to finding a solution through Rarchive, and can produce an upside-down version of what I'd like (levelplot() on the top - see code below). However, the following error occurs when I try and plot the xyplot() at the top:

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)

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 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

Hi, I'm setting up Samba with ldap backend and everythin appears to be working correctly except for profiles. Using: samba-3.0.2 openldap-2.1.26 smbldap-tools-0.8.4 When a user 'testa' tries to logon from a Win2K system that has joined the domain he gets the following error message: "Windows did not load your roaming profile and is attempting to log you on with your local

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
