Hello I have a multivariate data frame giving various responses for several treatments. I would like to plot the relationship in the responses in a pairs plot with different symbols for the different treatments. In a regular plot I would have used 'matplot' or just added the new treatments with the 'points' function. But how to do it in a pairs plot? Thank you for your

Hello! I am starting to use the lattice package. I generated an xyplot conditioned on a factor that has three levels: hence I get three plots in three panels spaces and one is left empty. I would like to add a plot to the empty panel space. Is it possible? Thank you

Hello R-help list I'm trying to run 1 billion iterations of a code with calls to random distributions to implement a data generating process and subsequent computation of various estimators that are recorded for further comparison of performance. I have two question about how to achieve this: 1. the most important: on my laptop, R gives me an error message saying that it cannot

Hello, I am having trouble figuring out how to create a color scale that will be consistent across multiple contour plots. What I would like is to plot a series of contour or image plots for different subsets of a data set but make sure that the color key stays fixed so that the plots are easily comparable. That is I need a map from the range of values of the entire data set to the color

Dear users, I am stucked with a programming problem: I am trying to download a squared adjacency matrix from matlab with only 0 or 1. Doing it without a loop at first, I get an error message that is, I think, related to the "mat_adj<-readMat(pathnames_adj)" line. Did anybodz encouter already that problem? If so, do I need to change anything in my code in order it not to be

Hello I have a matlab MAT file that contains one single variable: a. The structure of a is as follows: a.river1.flow (flow values) a.river1.date_flow (date) a.river1.precip (precipitation values) a.river1.date_precip a.river2.flow a.river2.date_flow a.river2.precip a.river2.date_precip I have used readMat to load the variable a in R, however I have no idea how readMat translates a. I managed

Hi to the list, I am trying to find a way to painlessly move structured data back and forth between R and Matlab (also Octave). For this purpose I found the R.matlab package great help. I wish to use a Matlab -v6 MAT file as an intermediary format, because it is well read by both Matlab and Octave. It is also well read by 'readMat' function in R.matlab package, but that is where I run

To make R.matlab's readMat work for me[1] I needed access to zlib's uncompress function. R already links with zlib, and sometime last year I hobbled together a quick package to get at a few functions. It's my first package, so I would love feedback both on the package and its purpose. I've dropped a temporary copy at http://jriedy.users.sonic.net/internalzlib_0.1.tar.gz Could

Hi, I am trying to load into R a MATLAB format file (actually, as saved by octave). The file is about 300kB but R complains with a memory allocation error: > library(Rcompression) > library(R.matlab) Loading required package: R.oo Loading required package: R.methodsS3 R.methodsS3 v1.2.0 (2010-03-13) successfully loaded.

Hi, Suppose I have a matrix of size 256x14x32 in MATLAB. I want to import that into R. I used readMat and then do.call. But the variable is stored as an array as its done in R. However, I want to define a variable W=array(0,c(256,14,32)) in R and read the multidimensional matlab variable into W. I am not able to do this in R. Please, could you help ? Thanks Gopi [[alternative HTML version

Is there any way to read these files (standard .mat files, created by matlab version 7 onwards are compressed)? I know that R.matlab doesn't read them (it even says in the file MatlabServer.m "Matlab v7 saves compressed files, which is not recognized by R.matlab's readMat()" (lines 47-8)). I know I should be able to make R call Matlab and transfer data (not that I managed to

Hi,all I have a problem running R.matlab package (under 2.10.1 version). I can set up the matlab server under local machine(run the MatlabServer.m), " And I can use setVariable and evaluate matlab functions in R. But when I ask Matlab to send the value back to R using getVariable function it always returns an error: " ??? Error: A MATLAB string constant is not

Dear R-people, I am trying to read a matlab file, unfortunately without success. I enclosed the zipped file. Do you have an idea how to read this file by ReadMat package into the R system? Thanks for your time! Wim Krijnen

Hello, I have problems running the R.matlab package. I work with R 2.3.1, under windows (using the Rgui). It seems that, even after loading the package, the "simple" functions such as writeMat() or readMat() are not recognized. For example, the following script leads to an error: > install.packages("R.matlab") --- Please select a CRAN mirror for use in this session ---

Does anyone know which version of Markdown is best for Wordpress? I see online that there are a few and was wondering which one people prefer. Also, is there any chance John Gruber will write an official Markdown plugin for Wordpress, given how popular it's becoming? -------------------------------------------------------- robdumas at gmail.com http://obnoxio.us/

Hi I am using Ubuntu 8.04 64 bit, R as below, Matlab 7.6.0. I would like to transfer mat files back and forward between R and Matlab. Whilst I have used Matlab for years its been a long time since I have used R (hence question may be a bit simple) Running code A <- c(1:10) dim(A) <- c(2,5) library(R.matlab) writeMat('A.mat', A=A) Does not appear to generate any mat file

Hello I need to run an r-file that works on Windows on MAC. The first lines of the file are: library(R.matlab) library(Rcompression) Somehow I cannot find where Rcompression is. Am I missing something? Many thanks Ed

Hi, I recently upgraded an older box running as a file server for a small company to Mandriva (Mandrake) 10.1. It's running Samba 3.0.10.1, the default Mandrake package. We have a custom script that mounts a Windows share using smbfs, backs up specific directories, and unmounts when it's done. The problem is, it's not mounting reliably. There is an entry in /etc/fstab for the

dear r-helpers, i created an object named A, which looks like this: A <- c("4.4","1.9","4.1") now i needed to get numbers instead of characters and for this i used the function: as.integer(A) which resulted in: [1] 4 1 4 My question is, why the numbers are rounded or more impotantly if there is a way to keep the decimal numbers? Thank you very much for
