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, after a debian upgrade my dev.copy2eps dont work anymore. I have this message: Error in matchFont(postscriptFonts(family)[[1]], old$encoding) : unknown font I try to change the font family in my .Rprofile: setHook(packageEvent("graphics", "onLoad"), function(...) { grDevices::ps.options(family="ComputerModern") } ) But it no fix

Hi, I would like to know whether it is possible to obtain a value of significance for random effects when aplying the lme or related functions. The default output in R is just a variance and standard deviation measurement. I feel it would be possible to obtain the significance of these random effects by comparing models with and without these effects. However, I'm not used to perform

Hi, I try to make a model using lmer, but the weigths is not accept. m1<-lmer(ocup/total~tempo+(tempo|estacao),family=binomial,weights=total) Erro em lmer(ocup/total ~ tempo + (tempo | estacao), family = binomial, : object `weights' of incorrect type I dont understand why this error, with glm this work. the total object is a vector. Any idea? Thanks Ronaldo -- God is subtle, but

Hi, anybody have a JGR launcher for linux? Maybe a script that launch JGR directly without open R then library(JGR) and JGR().

Hi, I need to add some different curves to a each panel in a xyplot. I have a old function to make this using panel.number, like this: panel=function(x,y,panel.number,...){ panel.xyplot(x,y,...) if(panel.number==1){ panel.curve(-655.8689+769.1589*log(5)+64.7981*log(x)-206.4475*log(5)^2) } if(panel.number==2){

Hi, If I have the follow situation: A dependent variable (i.e. number of insects) that is affected by an independent variable (i.e. rain). The problem is that the measure of rain affect the population in other moment. So there exit a lag between the rain and the number of insects. Exist in R any tool to find what is this lag? Explain better. Suppose that I have a linear relationship

...a, but the blue line (without intercept) is far from the observed points. Probably I missunderstanding some key elements in gam modelling or using incorrect syntaxis.

Hi, I just installed the last version of R taken from the CRAN mirron in University of Vi?osa, Brasil. Since I use Mandrake 9.1 I get the proper .rpm file. I installed fine and all the test runs OK. I tryied to install sevela packages ussing the install.packages("package.name") and the installation runs OK... apparently. However, when I try to use the new package I get the following

Hi, I made a survival analysis using survreg function. Its OK. But, I need to show in the graph 1-weibull curves. Ploting weibull curve a add the estimated points following these steps: fit <- survfit(Surv(Time,Censor)~Group) points(fit[1]) points(fit[2]) points(fit[3]) I have 3 groups. But I dont know how to plot the correct points on a inverse weilbull graph. I try to use

Hi, I write several xyplot graphics on a source file. When I try to use source("graphics.R") the source don't work, but if I use source("graphics.R",echo=T) it work. Generally some commands work without echo=T, but xyplot dont work. Why it dont work without echo=T? It is possible to write a source that dont need echo=T on source command? Thanks Ronaldo -- Aluno de

Hi, I am making some DNA distances and I would like to use dist.dna as matrix in R, but this command does not include models like GTR...
