Hi All Please see the Rprofile file which i have modified as follows and after that when I start R then I see that R says to me "TRUE" for all the packages implying that all loaded at once. But when i try to use commands as simple as help("lm"), it doesnt work nor any of the menu "Packages" is not working. Although the regression using lm ( Y ~ X ) is working

Dear R Developers, the following CRAN packages do not cleanly pass R CMD check for quite some time now and did not have any updates since the time given. Several attempts by the CRAN admins to contact the package maintainers had no success. norm, 1.0-9, 2002-05-07, WARN sound, 0.6, 2002-08-31, WARN Bhat, 0.9-07, 2003-11-04, WARN HI, 0.1, 2003-11-04, WARN mmlcr, 1.3.2, 2003-11-15, WARN mvnmle,

Thanks to Roger for pointing out the packages spweights and sptests to me. I believe they will be quiet useful in my work. But... I can't get them to work! Firstly, I realised that a newer version of R is available. I have now downloaded and installed it. When I try to 'install packages from CRAN' I get: trying URL `http://cran.r-project.org/bin/windows/contrib/PACKAGES' unable

Hi Every Body, I don't know why some regression functions have no related prediction function. For example lowess, loess, lokerns, lpridge, lpepa, and ksmooth. What could help? Is there any global or wrapper function so that can help? Regards, Amir Safari --------------------------------- [[alternative HTML version deleted]]

Dear maintainers and R-devel, Several orphaned CRAN packages are about to be archived due to outstanding QC problems, but have CRAN and BioC packages depending on them which would be broken by the archival (and hence need archiving alongside). Therefore we are looking for new maintainers taking over maintainership for one or more of the following packages: R2HTML SemiPar cghseg hexbin lgtdl

Dear R users, I am currently writing a MCMC algorithm for spatial Poisson model. One problem which I need to solve is as follows: I have a vector X[1:J] which describes characteristics of cells of a rectangular grid. Further, for each cell I have a list of adjascent cells adj[] and the vector listing numbed of adjascent cells num[]. Thus if I want to list cells adjascent to cell i I write

Hi, I am new to lattice graphics and have the following question.

I'm new to this site so I hope this isn't too naive a problem. I'm trying to use the permax function with a data frame containing gene expression measurements taken from 79 microarray experiments with >3000 genes per array. The data contains missing values and every time I use permax with the data frame I get the error: NA/NaN/Inf in foreign function call (arg 1) Could anyone

Sirs, I have recently been interested in your Maxstat. I have computed with my own programme the ranks (by using the Kaplan-Meier method and the log-rank test) with the formula (Observed-Expected)/(SQR Var). The results are similar but not exact to the M value obtained with the Maxstat. I would like to know whether you are using some correction or adjustment in computing the different ranks. Thank

Hello: I am using R 1.9.1 under windows. I am interested in the permax package for analyzing DNA microarray data. I see, from install.packages(), that the windows binary version is 1.2.1, but that source code exists for version 2.2. Version 2.2 has much more functionality, especially for clustered data. So, I wonder whether anyone has made a binary windows release for version 2.2 of this

Hello I am trying to draw a basic black and white map of two European countries. After searching some key words in google and reading many pages I arrived to the conclusion that persp() could be used to draw that map. I have prepared three small example files, which are supposed to be the files required for running that function. xvector is a vector with the longitudes yvector is a vector with

Hi all, I have a bit of a newbie question here that I hope y'all can help with. I've run a cluster analysis using hclust on about 500 objects (using R1.3 under Win 2000). The problem is that the tips of the dendrogram are so close together on the plot that the labels overlap and are unreadable. I've used "cex" to reduce the label sizes but this isn't sufficient with so

Hi R-users, I am new to R environment.I want to carry out a correspondence analysis on a contigency table with 64 columns and 298 observation of Environmental data.In many cells of the contigency table the frequency is just the value '1'.

Has anyone written subscripting methods for matrices which are indexed from zero? i.e. functions such as "[.zoffset" and "[<-.zoffset" which would allow, given an appropriate function "zmatrix" "zmatrix" <- function(...) { robj <- matrix(...) class(robj) <- "zoffset" robj } fred <- zmatrix(1:20, 4, 5) fred[0, 4] # would be 17

Hello Rprofessionals, The SOM-Obj works very well, when i normalize my data and the plot-function, too ! But i miss or didn't find the possibility , extract the information from the SOMplot "clusterSize" and "mean" for every cluster as quantitative information ( i.e. the DataFrame with an additional column which define the calculate clusters from SOM)? My intention -

Hi all I'm trying to create a three-dimensional wireframe-type plot, much like the screenshot shown at http://www.r-project.org/screenshots/volcano-persp.jpg In my case, I'm trying to show a density estimate of two-variable system, using the GenKern package. I've used the image() and contour() to create a nice shaded plot, but I've found a 3d plot is often easier for the

Dear R-list users, I'm new to principal components and factor analysis. I thought this method can be very useful for me to find relationships between several variables (which I know there is, only don't know which variables exactly and what kind of relation), so as a structure detection method. Now, I'm experimenting with the function prcomp from the mva package. In my source code
