Dear all, Every time that I need to generate I plot output as figure I use something like png("myoutput.png") plot(rnorm(100)*1.0,col=4) points(rnorm(100)*0.5,col=2,pch=0) dev.off() But now I need to generate a lot of outputs and it could not be done in a for looping where I can change the names. So I would like to know if is there a way of I automatically redirect the output from my

Dear R users: I have a dataset with two variables (>20000 observations, two samples from same subject) and I used "kernSur" from library(Genkern) to get a estimated bivariate density and corresponding plots as follows: new.data.normal<-data.normal[!is.na(data.normal[,2]),] x<-new.data.normal[,2] y<-new.data.normal[,3] op <- KernSur(x,y, xgridsize=50, ygridsize=50,

Hi list! I have prepared a custom function (below) in order to calculate separability indices (Divergence, Bhattacharyya, Jeffries-Matusita, Transformed divergene) between two samples of (spectral land cover) classes. I need help to cross-compare results to verify that it works as expected (since I don't know of any other foss-tool that will give me quickly some results). Does anybody

hi Juan, It is not so elegant, but work fine. I know that our colleagues can do it on a simple line. z<-c(526,723,110,1110,34,778,614,249,14) v1<-NULL v2<-NULL for (i in 1:(length(z)-1)) { for (j in i:length(z)) { v1<-rbind(v1,z[i]) v2<-rbind(v2,z[j]) } } df<-data.frame(cbind(v1=v1,v2=v2)) names(df)<-c("v1","v2") df$ratio<-df$v1/df$v2 Kind regards,

. "Saluton", Sorry by my poor english, I speak Portuguese. I does a captive portal using: - shorewall - dhcpd - thttpd (in port 8080) - maradns With Shorewall I use dinamic zones. The initial zone in shorewall is configured to redirects access to internal thttpd port 8080, that shows a login.cgi page. With thttpd I rewrite original url. The apache rewrite is very cool, but thttpd

Hi every body. I'm having difficulties to setup my filters correctly and I really need some help.

Thanks in advance, Thiago Abra sua conta no Yahoo!

Dear all, I have a dataset which I need to estimate the regression model and plot the estimated curve two other curves with low and high confidence interval (CI=95%). How can I do that? x<-1:100 y<-x^0.2+rnorm(100,0.1,0.1) mod<-glm(y~log(x)) plot(y~x) lines(predict(mod)~x,col=2) Kind regards, miltinho Brazil para armazenamento! [[alternative HTML version deleted]]
