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?

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....

Dear R-users, I successfully installed rtiff on by R installation, but when I tried to load it, I got: >local({pkg <- select.list(sort(.packages(all.available = TRUE))) + if(nchar(pkg)) library(pkg, character.only=TRUE)}) Error in dyn.load(file, ...) : unable to load shared library 'C:/PROGRA~1/R/R-26~1.2/library/rtiff/libs/rtiff.d...

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 d...

...ogram. My experience has been that this option often results in images of poorer quality, often with blurry contours, and a loss of resolution. A second and better option would be to make .TIFF files directly from the graphic output of R. I recently noticed that there is a library called "rtiff" that may be able to do this. However, I have not been able to get it to work, principally because I do not know how to install the required supporting software, libtiff and tiffio.h, correctly on my computer. I am running R 2.4.0 on a Windows XP machine. So far I have done the following: 1...

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 values between 0..1. This, in itself might not be a problem if the values obtained...

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

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

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
