Hello, I would like plot a vector and want to specify the Xticks which will be displayed. Is it possible ? For example, suppose that x is a vector of length 3. I just want the Xticks (and the corresponding labels) for 1 2 and 3 to be displayed ( and not 1, 1.5, 2,2.5, ....) .

Hi all, I have some some difficulties to use plot and its options. This is what i would like to do. I want to put three plot in a same window so i use par(mfrow=c(1,3)) and i obtain three columns for my three graphics. But, i would like that the two first take 90% of the window and the last 10%. Could anyone give me a soultion?? Best regards, Olivier --

Dear r-plus users, i would like to use outer in the following case outer(x,y,FUN="fun") i suppose that my function fun is of the following form: fun<-function(x,y) { if(y>x) return(x+y) if(y<=x) return(0) } My problem is that the command outer(x,y,FUN="fun") return me a null matrix instead of an upper triangular matrix. Is somebody have a solution ? Thanks for your

Dear R users, Suppose i have an A square matrix rxr. I want to obtain a block matrix B (pxr,pxr) where the p diagonal blocks are A and the others values are 0. I would like to do something like : diag(A,ncol=pr, nrow=pr) How can i do it ??

Daer all, Before to expose my problem, this the configuartion of my environment. I use the version 1.2.1 of R with a limux system (redhat) I have installed SJava (from omeghat) package successfully. So, i wanted to try an example (calc.R) that is provided in the library. This is the message I obtained: Error in isJavaInitialized("Java virtual machine has not been initialized. Call

Hi all, I have some (stupid) problems to display results and i don't find a solution. 1- res<-c(1,2,3) I would like to display >Results are 1 2 3 The following command cat(paste("Results are ",res,"\n")) give me >my results are 1 my results are 2 my results are 3 2- res<-cbind(c(1,2),c(2,3)) I would like to display >Result is the matrix 1 2

In general this is what "apply" does. In your example you could use rowMeans(ar) as well, I think.

Hi all, i would like to analyze some images with R. For example, i have a tif image (16 bit=2^16 values) that i convert in ascii file (8 bit =256 values only) so it is easy to work under R with image() function. But, i would like to keep my image with 2^16 values... how can i do to load my tif image in my workspace? Do you know if there is a package for analysis image ? Thanks Olivier --

Hi all, i would like to find the best way to resolve the following problem. Suppoose i have a vector x of length N with k different elements. length(x)=N u<-unique(x) length(u)=k I would like to get a matrix M with k rows and N columns such that: in each line i (i=1,...,k), which(x%in%u[i]) is equal to 1 and 0 else. Thanks for your help. Olivier --

Hi all, I would like to plot some points and define the bg color of my graphics. But the bg parameter set is defined for the. whole graphic. In fact, i would like to use something like : box(bg=gray(0.9)). So, the background concerns only the plot region and not the main title, the x title and the y title. The option col for the function box() concerns the contour and there is no option

Dear R-users, Using the plot function, I would like that axes are [-1,1] for x and [-1,1] for y. But when I use xlim or ylim, it adds automaticaly a small space (i.e. [-1.25,1.25]). I suppose that i have to use the fuction par() but i don't find the good parameter for this problem. So, how can i define the axes to be exactly [-1,1]. Thanks Olivier --

Hi all, I have some difficulties with the lme function and so this is my problem. Supoose i have the following model y_(ijk)=beta_j + e_i + epsilon_(ijk) where beta_j are fixed effects, e_i is a random effect and epsilon_(ijk) is the error. If i want to estimate a such model, i execute >lme(y~vec.J , random~1 |vec .I ) where y is the vector of my data, vec.J is a factor object

Is there any way to control the format of the axis label numbers on a plot? More specifically, I have some plots that get axes with label numbers in exponential format, and I'd like to change that to non-exponential. Thanks!! -- M.

Dear R users, I'm looking for a test of bimodality in order to make some decisions about how to procede with an analysis algorithm. I have not come across any such tests in my readings and discussions apart from the Rao which appears to be applicable to cyclic data. The data I'm interested in characterizing as uni- or bimodal are frequency x amplitude spectra of consonant speech sounds,

Hi Everyone, Does anyone know how to take the output of a 2D fft() and shift the DC component to the center? Is there a function that does that? if you know, please send me an email. thanks for any help! brad __________________________________________________ . http://im.yahoo.com -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

hi, all. I use R on a unix (linux) box and am quite happy with it. However, sometimes I need to create a graph that needs to be used with Microsoft Word or Powerpoint (ug). I can create a png or jpeg format picture, but the text look pretty crummy because jpeg is bitmapped. I can also create a PS/EPS version (my preference), but then it doesn't display properly in word or powerpoint (but it
