Hi, I have a question concerning color pallets. I am currently plotting geophysical fields with spplot (sp package) and I would like to create a pallet with open boundaries. For instance, I have a field whose values vary between -7 et 1, but a few values are much higher, for instance 28 or 32. As a result, I would like to create a palette with, for instance, 8 intervals within the range [-7,1]

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

Dear All, I was looking for the color index in?image function,?such as from topo.colors(n) and etc. but still never found it. For instance, from the help menu. ########################################### # Volcano data visualized as matrix. Need to transpose and flip # matrix horizontally. image(t(volcano)[ncol(volcano):1,]) # A prettier display of the volcano x <- 10*(1:nrow(volcano)) y

Hi, The script below is my current coding in order to produce a contour plot of temperature across altitude and time. In my case,?time,altitude and temperature?are represented by x, y and z variables. ############################################## Brazilan.Pallete <- colorRampPalette(c("blue","green","yellow","red")) image.plot(x, y, z, col = Brazilan.Pallete(50)) contour(x,y,z, levels = seq(1, 40, by = 1), add = TRUE, col = 'peru') ############################################## The plot worked fine but i...

Hi all, I was trying to draw a stacked density plot like that : library(ggplot2); library(plyr) dat <- cbind(rnorm(300), rep(c(1,2), each=150)) ggplot() + geom_density(aes(x=dat[,1], fill=factor(dat[,2]), position="stack")) + xlab("") + ylab("") + scale_colour_manual(name = "Pallet", labels = c("X", "Y")) Here

Is there a way to increase the "sensitivity" of the color palette in order to more clearly represent certain sections of data? For example I am wanting to clearly differentiate between height data for a rolling landscape but because of the extremes of the dataset (sea and mountain tops), the bulk of the landscape is shaded in closely approximating green - i have attempted to do this by

Hi list, I will help an person that will use some graphics of R in internet. But this pearson want to specify the colours. This person want me to create an pallete of colours like that: Name of color - Code - Colour White - 0xFFFFFF - color white (like an box with this color) I know that is possible with R, but i don't know how. Thanks for the advance. Atenciosamente, Leandro Lins Marino Centro de Avalia??o Funda??o CESGRANRIO Rua Santa Alexandri...

Hi, I was going to file a bug report for this, but I thought I'd check here first, because I'm not sure if this is a wine bug, or something to do with Photoshop or Compiz. Most times when I close Photoshop CS2, I'm getting the one or more of the tool pallets left behind on my desktop. I have found no way to get rid of them - apart from restarting the X server. I tried xkill but it

Hello, I am having difficulty obtaining the correct colors in my R charts. > colors()[c(552, 254, 26)] [1] "red" "green" "blue" But, if I specify col=552 in my barplot, I get gray bars. Likewise, col=254 gives bright pink, and col=26 is a red-orange. I get accurate results when I spell out the names, but I am making a pallet with 20- 30 colors and it is a

Let me take an artifical matrix : dat = matrix(rnorm(200*200), 200, 200) My goal is to visualize this matrix according to the procedure, described in previous mails. I took Mendelssohn's advice and got following advice : ?plot.im Z <- setcov(owin()) plot(Z) .................... etc However I can not reproduce this example in my problem. How I can change my data

Dear useRs, I got stuck trying to generate a palette of topographic colors that would satisfy these two requirements: - the pallete must be 'anchored' at 0 (just like on a map), with light blue/lawn green corresponding to data values close to 0 (dark blue to light blue for negative values, green-yellow-brown for positive values) - the brown must get darker for higher positive values. topo.colors() fails both require...

I used ?image function to do that, like below : require(grDevices) # for colours x <- y <- seq(-4*pi, 4*pi, len=27) r <- sqrt(outer(x^2, y^2, "+")) image(x, y, r, col=gray((0:32)/32)) However my next problem to add a color pallet for color description [as shown in following link]. If anyone here tell me how to do that, it will be good for me. Regards, Megh Dal

I've been using Wine and Linux(Fedora) for a couple of months now. The only program I'm using with Wine is Manga Studio. I've been having several problems with running it though. When it opens, all of the tool palletes would not be part of the main window, and I'd have to hide/show palletes to get them to show up. Well, today, I was messing around with the window options, and turned up the DPI setting, not knowing it would make everything HUGE. I can't get to the slide bar to turn it back down, and I...

I just managed to install Adobe Photoshop CS2 in Wine 1.1.3 and have a big problem with palletes with tools, layers, history and so on. They are disappearing behind the main window. When I resize it and bring palettes back to its place, they are disappearing again as soon as I set the last one. What can I do to make them behave like in Windows?

Hi, With help of AppDB howto and tips from wine community I managed to install Delphi 5 on KUbuntu 8.0.4.1 Wine 1.1.3. I can use it fairly flawlessly with some features missing. I compiled Application on this installation and launched in production also almost week ago and have not received any complaints till date. I have noticed some minor glitches which are hampering productivity a little bit.

...k it is because of the very small values (n=1000, min=1.222e-24 max, 1.890e-20). I used qplot(variable,geom="histogram")... If do it with the standard plot function it works perfectly. 2) I want to use scale_colour_gradient(). Is there any reference where I can find the predefined colour-palletes like rainbow etc. and how they look like? 3) How can I change the white grid in the background? In some cases I'd like to remove the white grid 4) How are the ticks on the X-axis calculated? Can they be changed in a way that always 5 ticks with the corresponding numbers (labels) are displaye...

Dear List, Is there a color palette avaliable similar to what is used in satellite ocean color imagery? I.e. a gradient with blue on one end and red on the other, with yellow in the middle? I have tried topo.colors(n) but that comes out more yellow on the end. I am looking for something similar to what is found on the CoastWatch web page:

Hello, I can't seem to add transparency to any color ramp I create using colorRampPalette(). Can someone tell me if it is possible to create transparent colour ramps? I am attempting to map shaded relief under elevation data. I know I can use the terrain.colors() with the alpha option, but I would prefer to create my own colour ramp using more vibrant colours. My most recent attempt at

has anyone in this list ever tried to make a javascript color picker something like http://www.daantje.nl/blog/index.php?buttonID=37 or http://typetester.maratz.com/ i just thought i''d ask before i force myself to doing this. thanks mark renn _______________________________________________ Rails-spinoffs mailing list Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org
