Hi everybody I was trying the R binary (1.7.0) for Macintosh (Carbon) and I tried to install some packages using "install.packages" and apparently this function was not implemented. I reloaded the base library since the "update.packages" function should be on it but did not work. Also I tried read.table and did not work either. Does anybody know if the base package

With the same system configuration (WinNT4 SP6 and 1.7.0), I get such a Dr Watson crash each time I try to use the Change dir... command in the File menu of Rgui.exe. I doesn't seems to happen if I do this immediately after starting R but well if I already did some computation. I don't have any problem by using directly setwd().

Dear R-helpers, I will like to know if there is a way to generate a stacked column graph using both patterns and colors to fill the bars. I have many categories for the number of color available in R, so I will like R to start with solid colors and then use patterns an colors. I have been using barplot and some code that I found in the archives, but I am still having bars with the

Our lab just picked up a G4 Powerbook (1 GHz, 1GB RAM, OS X 10.2.6). None of us have any experience with Macs but for various reasons we need to have one around for development. In any case, we've installed fink, all the Apple Developer Tools and the Dec2002updater to gcc 3.3. We're now trying to compile R 1.7.1 without too much success. First we had to get g77, which turned out to

Dear all, I am trying to generate bootstrap replicate matrixes (rows=samples, column=species, sampling with replacement) from a matrix dataset, but I do not know how to do it in R. I have tried boot() and bootstrap(), but they require an statistic, which in my case is cluster analysis (generating bootstrap values for a cluster analysis is a topic that has been mentioned previously in

Hi, Using Vegan package I was wondering if there's a way to use a distance matrix as an input for adonis (or any of the other similar hypothesis testing functions) instead of the usual species by sample table. Working in the field of microbial ecology, what I'm trying to do is to overcome the problem of having to use discrete units such as species or OTUs, which are problematic in

R gurus I have tried to install the R 2.0.1 binary for OS X and although the installation was successful I can get the application going. When I double click the icon R tries to load (R window shows briefly) and it quits immediately. This behavior was described in this list before and nobody found the answer to the problem. If you try to load the x11 version by typing "R" at

Hello, I've been trying to figure out how to access the individual elements from an object of class phylo. I am reading in 201 trees created by paup as below. > read.nexus("A_30knj_200t.txt", tree.names= NULL) -> anj30 > anj30[1] $tree1 $edge [,1] [,2] [1,] "-1" "-2" [2,] "-2" "-3" [3,] "-3" "1"

Estimados por solicitar su ayuda, estoy intentando cambiar el color de una etiqueta de un gráfico, he realizado múltiples intentos sin un resultado satisfactorio. Debido a que necesito realizar múltiples gráficos he realizado una función que dando parámetros de entrada me grafique las variables o los valores que deseo.

I'm working with samba 1.9.18p10-7, on a i586 with debian linux v2.1. I'm trying to personalize windows95/98 on a multiuser/shared PC instalation and I want to include a Historial folder somewhere in the home directory of every user on a centralized server. This way any user could log on from any PC (in a classroom for example) an may have their own configuration for the Internet

I'm sorry if the answer to my problem is buried in the archives. I have limited experience with R and I couldn't find a solution to my particular problem. I am running Mac OS X Aqua GUI v1.01 on a new G5 running os 10.3.8 with a 1.8Ghz processor and 1GB of sdram. I just downloaded bioconducter a week ago and I'm trying to cluster a matrix I created with a simulation with

Hello, I have been attempting to run a poisson glmm using lme4 for some time now and have had a lot of trouble. I would say 9 times out of 10 I receive the following warning: CHOLMOD warning: %h Error in mer_finalize(ans) : Cholmod error `not positive definite' at file:../Cholesky/t_cholmod_rowfac.c, line 432 My data are counts of microbe colony forming units (CFUs) collected from

I''m having trouble actually seeing a PCI device in my VMs. I''ve resolved several of my issues using previous posts and using the VTdHowTo wiki page. I have both VT and VTd BIOS options enabled. I have pciback hiding the devices and xm can list and assign the devices to VMs. I don''t see the PCI devices in my VMs though. I have tried a windows and a Linux vm, without

Hi Everyone, I posted this a couple of weeks ago with no responses. My interface (via gmane) seemed a bit flakey at the time, so I'm venturing to repost with some additional information. I'm trying to write selfStart non-linear models for use with nls. In these models some combinations of parameter values are illegal; the function value is undefined. That's OK when calling the

Estimados una consulta me encuentro graficando un histograma cuyos datos no provienen de una distribución clásica como la normal exponenial, poisson, etc, Lo que necesito es colocar una curva no paramétrica que permita evidenciar el ajuste de los datos a esa curva ya que son muchos (alrededor de 80000). Muchas gracias [[alternative HTML version deleted]]

Estimados su ayuda, tengo un total de 20 matrices las cuales deseo colocarlas como componentes de la lista, es decir matrices<-list(matriz1,matriz2,matriz3,...,matriz20) existe alguna manera de hacer esto de manera automatica ya que puede que exista un mayor numero de matrices por ejemplo 100, donde el ingreso de una por una puede resultar un poco cansado. A su vez a las matrices ingresadas

Hi, As part of my dissertation, I'm going to be doing an Anova, comparing the "dead zone" diameters on plates of microbial growth with little paper disks "loaded" with antimicrobial, a clear zone appears where death occurs, the size depending on the strength and succeptibility. So it's basically 4 different treatments, and I'm comparing the diameters (in mm) of

Estimados su ayuda con la ejecución del comando lapply() Tengo creada la siguiente función invertir(matriz,n) que me permite cambiar la posición de los elementos de una matriz. invertir<-function(Matriz,n){ a<-Matriz b<-matrix(c(rep(0,n*n)),n,n) c<-matrix(c(rep(0,n*n)),n,n) for (i in 1:n) {b[i,]<-a[(n+1)-i,]} for (j in 1:n) {c[,j]<-b[,(n+1)-j]} return(c) }
