similar to: densCols: what are the computed densities and how to create a legend

Hi, I was trying to make a 3D plot using densCols. The documentation for densCols doesn't look like it'll work for 3D. For example: ----------------------------------------- library(scatterplot3d) v1 <- rnorm(10000) v2 <- rnorm(10000) v3 <- rnorm(10000) ## 2D with denscols mat1 <- cbind(v1,v2) mcols1 <- densCols(mat1) plot(mat1,col=mcols1) mat <- cbind(v1,v2,v3)

Hi, I have been trying to plot density plots using the example on: http://addictedtor.free.fr/graphiques/graphcode.php?graph=139 I used to use this function, but I cannot get any old code or even the example to work. library("geneplotter") require("RColorBrewer") x1 <- matrix(rnorm(1e4), ncol=2) x2 <- matrix(rnorm(1e4, mean=3, sd=1.5), ncol=2) x <-

Hi, I want to make a plot similar to sm1 (attached). The code I tried is: dcols <- densCols(x,y) smoothScatter(x,y, col = dcols, pch=20,xlab="A",ylab="B") abline(h=0, col="red") But it turned out to be s1 (attached) with big dots. I was wondering if anything wrong with my code. Thanks,Zhengyu -------------- next part -------------- A non-text

Dear listers, After activating the name space for my bioconductor package (prada) I successfully ran R CMD check. However when loading the package in R and running the examples the imported function brewer.pal from package RColorBrewer is not found. I can directly call brewer.pal from the RColorBrewer name space typing RColorBrewer::brewer.pal, but it is not imported into my prada name space. When

I'm hoping that someone could guide me in how to extract data from shapefiles. I want to extract data from a shapefile (classed as "SpatialPolygonsDataFrame") and more specifically, the data is contained within the slot called "coords" from the class "polygons" within this file and despite my best efforts (and much reading!), I'm at a lost. Many thanks, Kate

Hi: Is there a way to get smoothScatter to not clip when I increase the xlim and ylim parameters? Consider the following example: set.seed(17) x1<-rnorm(100) x2<-rnorm(100) smoothScatter(x1,x2) #Now if I increase xlim and ylim notice that the plot seems to be clipped at the former xlim, and ylim boundaries: smoothScatter(x1,x2, xlim=c(-5,5), ylim=c(-5,5)) Thanks.

Hello, I have found that in smoothScatter it is not possible to reverse the axes plotted (R version 2.9.0) .   It appears that this arises from the hard coding of xlim and ylim in smoothscatter.R in the lines : x <- x[ xlim[1] <= x[,1] & x[,1] <=xlim[2], ]   (line  number 25) and x <- x[ ylim[1] <= x[,2] & x[,2] <= ylim[2], ]  (line number 31) This results in a x

Hi I would like to implement the "Earth Movers Distance" into R and found the code in C on the following page: http://www.cs.duke.edu/~tomasi/software/emd.htm Unfortunately, I don't know much (nearly nothing) about C and how to call it from R. As far as I have seen, the calling of the code from R should be rather straight forward, but there are still several things I don't

Hi, I am using the densCols to draw a high volume scatter plot. Instead of using the default local density, I would like to take log of the local density and then map them to the colors. I could not figure out how to do that. For example: plot(x,y,col=densCols(x,y,"log")) ? Any help would be appreciated! Jiaxiu [[alternative HTML version deleted]]

Hi all, I am using the vegan package to run a prcincipal components analysis on forest structural variables (tree density, basal area, average height, regeneration density) in R. However, I could not find out how to extract factor loadings (correlations of each variable with each pca axis), as is straightforwar in princomp. Do anyone know how to do that? Moreover, do anyone knows

Hello How to compare  two statistical histograms? How i can know if these histograms are equivalent or not??   Regards [[alternative HTML version deleted]]

I am being barraged with Ruby, Rails and Rich Internet application work right now. Almost enough that I could quit the day job and make a go of it, forgetting about Java altogether. Places in the greater Miami area are turning on to Rails and Ruby -- much of it fueled by the stronger voices in the local Java community. Am I alone in this, or do many of you see absolutely explosive growth in Ruby,

Im currently making a game called Risen to work . The only problem ive got its that the mouse doesnt work wothouth a patch . But with this http://bugs.winehq.org/attachment.cgi?id=27496&action=edit patch it works but when i stop the mouse it just keeps spinning , can someone help me get this patch to work with the newest (1.3.9 ) wine and get the patch work better ? Or is it a better

Hi All, I have a for loop inside the function and I cannot get UUU to give me an updated grid.dens object when I run the function (it does update when I run just the for loop). Here's a simplified version of my function: UUU=function(pop, grid.dens) { for (i in 1:10){ Food=grid.dens[pop$yloc[i],pop$xloc[i]] #use initial grid.dens values Consumed=(pop$weight[i]*0.25) Left=Food-Consumed

Dear R users, I'm trying to create images of 2 symmetrical matrices using heatmap.2 of the 'gplots' library. Both matrices have the same row and column names For the first matrix I'm using the default clustering and column denrogram options: heatmap.2(Matrix1, symm=T, breaks=20, col=rich.colors(19), main="matrix1", density.info="histogram",

Dear R-devel, my Bioconductor EDASeq package has a function MDPlot that uses the smoothScatter() function from the graphics package.
