Hi again. Thank you for the tips but I don't know what is a X server. I remember that I?m working with my own notebook. Is this possible? I could also try to run it in my faculty. thanks Luis -------------------------------------------- sapo.pt/kitadsl -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Dear helpers, I'm working with expression matrices (DNA microarrays) and my professor suggested me to investigate the possibilities of Xgobi. Searching the net I found that I could use it with R. Is that true? How can I do this? I'm working on a Windows ME notebook. I've already got xgobi.zip from CRAN and xgobi.zip from Professor Brian Ripley

Dear R helpers I would like to make a plot where the symbols were the numbers of the corresponding classes, i.e, samples of class 1 would the symbol 1, samples of class 2 would have symbol 2,.... Is this possible? Thank you Luis -- Kit SAPO.ADSL.PT Apenas 50 ?. Adira j? em http://www.sapo.pt/kitadsl

Hello I was doing PCA (principal component analysis) with a DNA expression matrix (7000 rows/38 columns; from golubEsets) but I had the following problem "Error:cannot allocate vector of size 397051 Kb In addition: Warning message: Reached total allocation of 119Mb: see help(memory.size)" I've already done some filtering (reduced to 3051 rows) but the problem remains, only the

Hi again, Thanks for the tips on Xgobi. I'll try them. Now I have another question. There is a package (not submitted to CRAN yet), that I would like to use, but it has the extension .tar, so it's for Linux platforms am I rigth? Is it possible from those files to compile for Windows? Nice weekend for all Luis -------------------------------------------- sapo.pt/kitadsl

Hello! I need to classify a data set with 19 variables and 9 classes using Logistic Regression(on R). I know that when we have only 2 classes we can use glm() to estimate the coefficients of the model. But I don?t understand how can I do a classification task with Logistic Regression on a data set with 9 classes! Does anybody know how can I estimate these coefficients (of a model with 9

Hi, I would like to rotate the x axis tick labels by 45 degrees. Using the code below, could someone please provide an example? Many Thanks In Advance, Alex library("scatterplot3d") mydf=data.frame(rate=seq(158, 314) ,age=seq(1, 157) ,market_date=seq(as.Date("2000/1/1"), as.Date("2003/1/1"), by="7 days"))

I would like to plot points in 3D and then be able to rotate the plot in real time in order to understand the distribution of the points using the visual parallax that results from the rotation. The R-package scatterplot3d will plot in 3D, but I've not found a way to rotate the results in real time. (It also does not seem to get the projection from 3D to a viewing plane right.) The R-package

Hi again With arima0 the problem was solved but what are the diferences between arima and arima0? I have another question. I fit the model to the data and I make some predictions. But I also want to calculate MAPE based in the last 3 observations available. Is it possible? Can I obtain the fitted values from the model? thanks~ luis -- SAPO ADSL.PT, apanhe j? o comboio da Banda Larga. Kit

Hi Alex, this should be related to the "las" argument of "par()" but actually it does not seem to be parametered in scatterplot3d. Searching the net for "scatterplot3d las" provides a link to: https://stackoverflow.com/questions/25458652/specifying-the-orientation-of-the-axes-labels-in-scatterplot3d You may try the solution that is provided in this link or consider

I don't understand where is my problem. I tried the problem suggested by Prof. Brian Ripley data(USAccDeaths, package="ts") and it worked. So this is not a machine or configuration problem.

Many Thanks In Advance, Alex 45 degree rotation is not supported in base R graphics and scatterplot3d uses that. You can use par(las=2) before your code and get them rrotated by 90 degrees, or you can add

Dear helpers I have this code to make 10 plots in the same device a<-1 split.screen(c(2:5)) for (i in 1:10){ nova.matriz<-a*sigma+(1-a)*S proj<-calculo.comp(treino,nova.matriz) print(proj[,1:2]) screen(i) plot(Re(proj[c(2,3,6,9:11,14,23),1:2]),xlim=range(c(- 15:15)),ylim=range(c(-5:5)),col="black") points(Re(proj[c(1,4:5,7:8,12:13,15:22,24:27),1:2]),col="red")

Hello R-users! I am trying to plot 3 vectors (x,y,z) of observations generated by mvrnorm in library(MASS). I tried plot3d in library(djmrgl) and scatterplot3d. But these program gives x,y,z axis which do not intersect at the origin (0,0,0). I searched through all the graphics related packages for R like xgobi, ggobi, grid and more. Quite confusing which one to choose. Would anyone recommend

Dear helpers Does R have a package that performs projection pursuit density estimation? Or anyone knows code in Matlab or C for example to do this? Thank you all Luis

Hi, I am doing my way on R, with much experimenting. So, I am trying to plot a 3d graphic ussing "persp" and entering a data set (attached) of UTM coordinates as x,y and a pH values as z. However when I try an error message comes out telling that increasing x and y values are expected. Jus ordering the first vector does not help, and, of course, order the first two independently

Hi all, I've tried to make a 3D plot, but have run into some problems. I'd like to have a plot that I can rotate interactively using the mouse, which is possible using the plots3d {R.basic}. However, I would like to change the symbols used as the points, but there's no pch in plot3d(). If I use the Scatterplot3d package, I'm able to change this, but not able to rotate
