Hello all, i am using Ubuntu 12.04 and I have R 2.14.1 When i try to install the rtiff package I got this error: > install.packages("rtiff") Installing package(s) into ?/home/lapalmejo/R/i686-pc-linux-gnu-library/2.14? (as ?lib? is unspecified) --- Please select a CRAN mirror for use in this session --- Loading Tcl/Tk interface ... done trying URL

I wanted to ask Eric a question or two about the rtiff package, but his listed email address bounces w/ 550 error. Does anyone know how to reach him, or whether he's actively maintaining rtiff? If anyone's interested, my primary desire is for rtiff (or other tool) to provide me with the raw range of pixel values in a tiff file. rtiff dumps straight into a pixmap object, so the

Many medical journals and publishers require that images, whether photographs or line art, be submitted as high resolution .TIFF images. One option for R users is to produce an image in one format and to convert it to a .TIFF file using a second software program. My experience has been that this option often results in images of poorer quality, often with blurry contours, and a loss of

Dear all, I have been trying to speed up a process we have been done in ArcGIS. We have to read a single layer TIFF (monochrome image) in . For this, I have used the "rtiff" package. After reading the TIFF file, I compared the raw values for each pixel that I have in ArcGIS to the ones obtained in R. In ArcGIS I have discrete values in the range 0..255, while in R I have continuous

Dear R-help I want to display an image file in a new plot frame. SVG is my preferred format, but I can also consider PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick). By way of background (although not material to this posting), the image file is generated by a call to 'dot' (part of the 'Graphviz' suite) after the required .dot file has been produced using hand-crafted R code.

Since requests keep trickling in, I have finally gotten around to polishing my rtiff package for R. This package will read TIFF images into a pixmap for subsequent processing. However, I am encountering a couple problems with compiling the shared library. 1. On windows (R 2.2.0): R CMD INSTALL successfully compiles a dll, but the dll has no entry points (as revealed by nm rtiff.dll), leading to

Hi, We have recently been using the tiff package for reading tiff images into the Bioconductor Package EBImage. This has been extremely helpful in conjunction with other steps to eliminate dependencies on ImageMagick. However, it seems that 12-bit images are not supported. We were wondering if there are plans to extend the functionality of the readTIFF() function in the tiff package to

For some reasons the afs tokenforwarding stuff has changed siginificantly from v 2.9p2 to 2.9.9p2. This makes it impossible to use public key authenticication in a standart AFS environment. I don't know the reasons for these changes. In any case attached is a patch which restores the old behaviour. Regards Serge -- Serge Droz Paul Scherrer Institut mailto:serge.droz at

Hi, I output multiple "grid-package-based" plots to the postscript device. Because the graphics are complicated and consists of a lot of datapoints (~200'000) the files become really big. To avoid this big files and to shorten the creation, I currently print the plots to the png device and manually combine them into one multipaged pdf document. My question is, it is possible to do

I only recently discovered options("available_packages_filters" = list(add = TRUE, "license/FOSS")) [cf. help("available.packages", package="utils") in R 2.10.0 or later] which goes nicely with my options("checkPackageLicense" = TRUE) [new in R 2.11]. But now I want to purge my library of packages I would not have installed had I known about

OpenSSH 3.7 has just been released. It will be available from the mirrors listed at http://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. We would like to thank the OpenSSH community for their continued support to the project, especially those who contributed source and bought T-shirts or

Hi, I've been looking for Image Processing packages. Thresholding, Edge Filters, Dct, Segmentation, Restoration. I'm aware, that Octave, Matlab etc. would be a good address but then I'm missing the "statistical power" of R. Does anybody know of packages, projects etc. Comments on wether the use of R for such matters is useful are welcome. Greetings Thomas Kaliwe

Hello, The ssh deamon from OpenSSH_2.5.2p2 first does a seteuid(uid) and then stat($HOME/.shosts) to check whether a .shosts file is there. This seems to be a problem when homedirectories are only accessible "by group permission"; for example in the following (as I guess quite common) case: drwxr-x--- root mygroup 512 Apr 10 12:09 mygroup And my personal homedirectory would now

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

Hi all, I'm wondering if there is a way to define a destructor function (to free memory) for S4 class objects in analogy to C++? rm() combined with gc() does not seem to be a good idea (Chambers, 2008). So could it be done on the C/C++ level or is it even already available in the "internals"? Many thanks, David [[alternative HTML version deleted]]

Dear all, I get the error "Error in namespaceExport(ns, exports) : undefined exports function1 , function2" when compiling or even when I roxygen my package. The two function I once had in my package but I deleted them including their .Rd files. I also can't find them in any other function or help file. So does anybody know where these functions are still listed that causes

All, I have a question regarding colors in bar plots. I want to stack a total of 18 cost values in each bar. Basically, it is six cost types and each cost type has three components- direct, indirect, and induced costs. I would like to use both solid color bars and bars with the slanted lines (using the density parameter). The colors would distinguish cost types and the lines would
