I am out of my league with this question. The following code starts the java imaging program ImageJ from within R, and displays an image (assuming ImageJ is installed on your computer). library(RImageJ) img <- IJ$openImage( file.choose() ) #pick an available .tif file img$show() # make the image object visible # An image is now displayed # find out about the objects involved >

Hi all, I intend to use R for some image manipulations/analysis. It's relatively straightforward to read and manipulate image files in R, but I also would like to store the resulting image (after manipulation) as a bitmap image with the same resolution as the original image. Here is a simplified version of what I'm working on: # Start example require("RImageJ") # first open

Hello everyone! I have two questions regarding cluster analysis with the package 'cluster' : 1. I have a dissimilarity matrix in csv format, and I would like to use it to generate a dendogram using 'hclust'. How do I make that matrix compatible with the function? I think it has to be similar to the objects generated by the 'dist' function. Any ideas? 2. Does

Dear Mailinglist, I just set up an R 2.9.1 environment with Rcmdr 1.4-6 on Ubuntu Jaunty 9.04. As I'm from Germany my $LANG variable is set to "de_DE.UTF-8". Now, when I open up Rcmdr and try to edit a new datamatrix there is no edit window appearing: Datenmatrix <- edit(as.data.frame(NULL)) ERROR: invalid device In addition, there are plenty of warning messages in the

Hello, I've uploaded the initial release (0.0-142) of the RImageJ package to CRAN. The package allows R to use the facilities of the java based image processing and analysis platform ImageJ.

Dear Rxperts, Through Windows OS, I created shortcuts (paste as shortcut) to excel spreadsheets ( with "xlsx" as the file extension). I wasn't able to read the shortcuts through R and using "read" functions of "xlsx" package. exf <- "a1.xlsx.lnk" > read.xlsx(exf,1) Error in .jcall("RJavaTools", "Ljava/lang/Object;",

I should have this in my head by now... I tried migrating a physical Windows host last night using virt-p2v CD. It ran for 3 hours and then died. I'll get details later from the log but as I think about it, I'll bet it died because I never installed virtio-win in my Fedora migration server. The documentation says do "yum install virtio-win" - but this is RHEL

Dear all: I have a shapefile in UTM coordinate system and I would like to transform it to Lat/Log coordinates (WSG84). The package PBSmapping contains function convUL to transform between the two coordinate systems when data is in the form of a data frame with attributes specifying the coordinate system. However, when shapefiles are imported using function read.shape (package maptools), a list

Dear R-users: Sorry to bother so late with this question, which surely has simple answer. I'm working with matrices that contain either "1" or "0", for example: [,1] [,2] [,3] [,4] [,5] A 1 0 1 0 0 B 0 1 0 1 0 C 1 0 1 0 0 D 1 1 1 0 1 I want to count the number of "1" common to, say, A and B, the

Hi, I'm trying to use the data which I generate within R to make images in .bmp format to be lateron printed by a printer. My first thought was the RImageJ package, but this seems to be discontinued. What I am currently doing is generating a matrix of grey values, which needs to be parsed into the right image format. Is anyone aware of a package or rather "easy" way to generate

Dear R-experts, I'm a new R user and so far have no complains about ir. However I still can't figure out how to install packages. I'm running the R 1.5.0 (Carbon) under OS X. I just downloaded some packages from CRAN (Tree, among them) and moved them to the library folder in R. When the R session started, I was expecting that using the command library(tree) would do it, but

still working on solutions to this error, when running a company specific software program. the program runs fine (it's a multiple choice exam), but errors as it tries to collate the results (only when the result is a pass). one possible reason is "The error is caused by Access trying to store a variable in a datatype that is too small for the variable", linked to use of

Proceed at your own risk as iplots cannot resolve potential ev.loop
