...1] "x" "y" "z" and suppose I want to put these objects inside a list object, say object.list <- list() without having to explicitly write down their names as in object.list$x = x object.list$y = y object.list$z = z Is this possible?

Hi! I was wondering if there are any other functions for numerical integration, besides 'integrate' from the stats package, but which wouldn't require the integrand to be vectorized. Oh, and must be capable of integrating over (-inf,+inf). Thanks in advance, Eduardo Horta [[alternative HTML version deleted]]

Hello, Are there any packages which allow for a good integration between R and LaTex / LyX? I'm interested mainly in automatic (automagic?) imports of plots/graphics. Thanks in advance and best regards, Eduardo de Oliveira Horta [[alternative HTML version deleted]]

...)) } but obviously this doesn't work, since Y[[1:n]] is not allowed at all. Any elegant suggestions? I really would like to avoid something like Ybar<-function(u){ for (i in 1:n){ Ybar<-Ybar + Ybar[[i]](u) } Ybar<-1/n*Ybar } Thanks in advance! Best regards, Eduardo Horta [[alternative HTML version deleted]]

...if don't remove the object i, it ends the loop with value equal to 10 and then f[[1]](t)=f[[2]](t)=...=f[[10]](t)=t^2+10. I am aware that I could simply put f<-function(u,i){ f<-t^2+i } but that's really not what I want. Any help would be appreciated.

...colour="red") Error: ggplot2 doesn't know how to deal with data of class numeric but it seems that the "data frame restriction" is really very restrictive here.

...ervations (this reflects the fact that the market may open and close at varying daytimes). I have guessed that a list would be a better way to store my data, since a matrix would be filled with NA's and that is not exactly what I'm looking for.

...ple 'solutions', for example to set g<-function(u){ vec1<-drop(coeff) vec2<-drop(zeta(1:4)(u)) g<-drop(crossprod(coeff,zeta(1:4)(u))) } as well as using the %*% operation, but these won't solve my problem. Any suggestions would be welcome. Thanks in advance, Eduardo Horta [[alternative HTML version deleted]]

I would like to know if there is any sort of fixes to this problem, such as specifying the symbols font or embedding fonts into the pdf file. Any help would be welcome.

Hello, I want to save a pdf plot using Cairo, but the canvas of the saved file seems too large when compared to the actual plotted area. Is there a way to control the relation between the canvas size and the size of actual plotting area? Thanks in advance, and best regards, Eduardo Horta [[alternative HTML version deleted]]

Hello, I need to unsubcribe this email to the R help mailing list because I need to create an email only for this mailing list. My email account doesn't have that much space anymore and I don't have access to this every day. How can I do that? Thanks a lot -- Bárbara H.

Hello, I'm willing to plot a sequence of densities on a 3d graph, something like ----------------------------------------------------------------- x <- sapply(1:10, function(i)rnorm(1000)) f <- sapply(1:10, function(i)density(x[,i], from=-5,to=5)$y) grid <- density(x[,1], from=-5,to=5)$x win.graph() persp(grid1, 1:10, f,theta=-50, phi=30, d=2)

Hi everyone, Do you know how to apply a If command to a vector in a data.frame, creating a new column? Example: If one species has "1" value in the Abundance column then it is "Solitary". If the abundance is higher than 1, is "School". I did: aggregationFunction <-function(x){ (if (x>1) a<- 'School' else a<-

Hi, I have a data frame with several factors and I want to count the occurrences of an event resulting from an interaction of some factors. I tried to do several tables (and then converting to d.f and then merge them by one factor and the freq Tab1 <- merge (BPorAmost,BPorSector,by=c('Sample','Freq')) Tab1 <- merge (Tab1,BPorDist,by=c('Sample','Freq')) Tab1

Tinn-R (http://www.sciviews.org/Tinn-R/) is one of the topmost suggestions when googling an R-(text-)editor for Windows. However, to me it appears dissappointing that Tinn-R does not handle utf-8 (mac-roman, or any other) encoded R-scripts or, in general, text files. Besides Emacs and the R built-in editor, could you recommend a good editor for Windows, even some commmercial for a small
