Hi, i created a graph with heatmap(sma) function: heatmap(dataHeat(x)) and I wish to change the gradation of colors from blue to red, how could i do? Using "heatmap(dataHeat(x), col=c(2,4))" i will use only 2 colors without gradation. Ty so much Andrea

Hello I have a problem on keeping the format when I export a matrix file with the write.table() function. When I import the data volcano from rgl package it looks like this in R: > data[1:5,] [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [,13] [,14] [1,] 100 100 101 101 101 101 101 100 100 100 101 101 102 102 [2,] 101 101 102 102 102 102 102

Hi Folks, I'm trying to get rgl.Sweave to produce plots with transparency. However, it just seems to produce opaque plots when pdf is the output type. Perhaps this is a known issue? I'll just use .png in the meantime, but wanted to see about this, as I didn't see it in the documentation (though it's possible I missed it). Thanks, Allie \documentclass{article} \title {rgl

Hi, I am applying the following code to map pca loadings onto a 3d grid, my problem is this - the output only plots the spheres in the requested color (in this case "red") for the first argument. The sphere from the second argument appear as flat dark circles. Also the text3d() command only seems to work for a couple of the positions, with no text added in most cases. Could anyone offer

Hello everybody, I'm trying to create my own color palette on R, in order to interpolate some different temperature data on different maps (daily means, seasonal means,...). I would like to create a color palette which works for each map, so I need a color palette between -40 and +40?C. Sometimes my data for one map range from -10 to +20, sometimes from 10 to 30, etc... but always between

Dear list Is there any way that I can color the background (not the plotted points) of each box in "pairs" ? I'd like to color them according to the correlation coefficiency of each data pair. thanks. N

Hello: I have a tab delim file with 100 rows and 100 columns. I have numerical values in this table. What I want is to create an image color map with color gradation. my values range from -5 to 0. max value is 0. to acheive this, I need to convert my data.frame into matrix. I tried following : mydf <- read.table('mytable',sep='\t',header=T) mydf1 <- mydf[,2:100]

Hi, I hope to show a heatmap with thre colours, no gradation. How to specify heatmap.2 to map "green" for values less than -1, "gray" for values between -1 and 1, and "red" for values greater than 1 ? Thanks [[alternative HTML version deleted]]

http://www.nabble.com/file/p25336596/Conductivity1.jpeg I need a little help making modifications to the image included with this post. First, rather than using a linear color legend to display the output I would like to use a log-scale legend. Thus, the legend on the right would go from 1 to 1000, for example, with a classic log-scale gradation. What I hope to avoid is taking the log of the

Dear R list I am using rgl.sphere to visualize scatter plot data in three dimensional space. Thanks to the rgl library, I can easily find out the data point that I am interested in. However, as I can not see the labels of each data point directly in RGL window, I usually look for the values of x, y, z axis to find out the label (or line number of the data point). Is there any way that I

Is it possible to see the source code of the open-sourced SVML? The diff file does not include the library. I searched the Internet but I could not find.

Hi all, Okay, the point is whether Intel will publish the source code for their SVML. If Intel will make SVML open-source, there would be not much advantage in incorporating SLEEF into LLVM, since it would be also fairly easy to port SVML to other architectures. If Intel will not open-source SVML, then there could be advantage in using SLEEF for x86 by inlining the functions. Is it possible

Dear LLVM contributors, I am Naoki Shibata, an associate professor at Nara Institute of Science and Technology. I and Hal Finkel would like to jointly propose to add my vectorized math library to LLVM. The library has been available as public domain software for years, I am going to double-license the library if necessary. ******** Below is a proposal to add my vectorized math library,

Hi everyone, I think that everyone is on the same page. We'll put together a patch for review. One remaining question: There seem two potential homes for this library: parallel_libs and compiler-rt. Opinions on where the vectorized math functions should live? My inclination is to target it for the new parallel_libs project, in part because I feel like compiler-rt has too many things grouped

I should keep quiet and leave well enough alone, but playing devil's advocate for a moment - I see you didn't bundle this with compiler-rt, which I guess is good? In the end what was the reasoning for that? Do you see this being sufficiently independent and running a different development track that it made sense? 1) Why rename C files to C++ (consistency?) 2) It seems your

Hi Amudhan, Please go through the following that would clarify up-gradation concerns from DHT to RIO in 4.0 1. RIO would not deprecate DHT. Both DHT and RIO would co-exist. 2. DHT volumes would not be migrated to RIO. DHT volumes would still be using DHT code. 3. The new volume creation should specifically opt for RIO volume once RIO is in place. 4. RIO should be perceived as

I think I reported this bug in the past. At that time, I was told that it is a bug of autoconf. ./configure does not recognize Linux on DEC Alpha 21164PC (a cheap version of Alpha EV56), so all the compilation flags were set incorrectly. I don't know the right way to fix it (I don't know how autoconf works yet ...), but the following patch fixes the problem. Thank you, Naoki Naoki

Hi R users and experts, I am interested in learning more about the use of 3D plots. Specifically, I want to add points and lines to a surface plot. And get the axes and labels plotted also. Here is what I have tried with an example data set : library(rgl) vol2 <- 2*volcano # Exaggerate the relief library(reshape) mvol2 <- melt(vol2) str(mvol2) # First, persp and persp3d plots do not succeed
