Error in RImageJ
Hello everybody, I'm running R under Mac OS 10.6.3 on a MacBook 2.16 GHz Intel Core 2 Duo. I've recently installed R 2.11.0 and the RImageJ library v. 0.1-142. When trying to follow the example given in the package manual and I get the following error: download.file( "http://www.google.fr/intl/en_en/images/logo.gif", dest = "google.gif" ) trying URL 'http://www.google.fr/intl/en_en/images/logo.gif' Content...

RImageJ initial release
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.

Generating 1-bit and 8-bit BMP files using R
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 these images using R? Many thanks, Ingo [[alternative HTML v...

Remove all spaces from a string so it can be used by assign()
Hi I have a string "56 Fe [1]" that I would like to use as a variable name by using "assign" however I think the spaces and brackets might be causing R some trouble. How can I change the string so that it just becomes 56Fe1 and can be used as a variable name. Thank You Kurt _________________________________________________________________ [[elided Hotmail spam]]

Is it possible to save raster data as a bitmap?
...#39;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 image and store as raster logo <- system.file("images", "R.jpg", package = "RImageJ") img <- as.raster(IJ$openImage(logo)) # do some modifications modify <- as.raster(matrix(hsv(1, 1, 0.5 * rgb2hsv(col2rgb(img))[3,]), nrow(img), ncol(img)...

RInside & child threads
Hi Folks, I am creating a multi-threaded C++ application that initializes RInside in one of the child thread. I would also like to access support interfaces like Rcpp::Environment in the remaining child threads, so that I could access any "R" function associated with the environment initialized. When I run my program, I always get "C Stack limit too huge" errors. I looked

Package 'operators'
Folks, In brief -- how many of you have found the 'operators' package to be valuable in their work? Not that I lack respect for the amount of work involved in creating and maintaining a package, but I am unsure about the utility of these new operators. Several of the operators appear to offer different ways of accomplishing tasks that are already relatively easy in base R -- regular

Creating Rcpp RcppDatetime from string with millisecond
Hi, I was trying to generate RcppDatetime from a string. The main problem for me is that my string contains millisecond. I saw that RcppDatetime takes in double of seconds since epoch. I try to generate a double using boost but has no success. I'm wondering if you have any sample snippet? The string looks like: "2010-03-18 15:50:51.232" Secondly, what time zone RcppDatetime is

JRI API: sourcing from Java String
Hi all, I have been using 'source(filename)' to load R code from a file object. However, now I have a special case where I don't have a file since I am loading an R script from a Jar file. I would like to avoid creating temporary files. Is there a way to use the 'source' command with a Java String? Are there any other, better ways to do that? Ralf

how to create a SEXP which could be accessed in embedded R
Hi all, I am not familiar with writing R extensions. In a C program, I want to create a SEXP and access it in embedded R. How to let the embedded engine know there's a new vector? For example, after creating a SEXP, parsing 'ls()' in embedded R and then evaluating, STRSXP returned will contain the name of the SEXP. Any help would be appreciated.
