Hi, I was able to connect to a MySQL database (called "zooscan" and with a table "serie" under Win XP with R 1.6.2 using: > library(DBI) > library(RMySQL) Warning message: DLL attempted to change FPU control word from 8001f to 9001f > drv <- dbDriver("MySQL") > con <- dbConnect(drv, dbname="zooscan") > dbExistsTable(con,

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

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, Maybe this is more a programming questions than a specific R-project question, but maybe there is someone who can point me in the right direction. I have a picture of cirkels which I took with a digital camera. Now I want to use the diameter of the cirkels on the picture for analysis in R. I can use pixmap to import the picture, but how do I find the outside cirkels and calculate the

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]]

Dear all I tried to find some packages (or programs) for image analysis and especially fractal dimension image analysis but so far I had not success. It shall be used for particle surface layer analysis from TEM images. Any suggestions? Best regards Petr

What software exists for digitizing video to quantify the motion of specific features in the image? I might be willing to use something that's NOT in R, though I'd prefer something in R (or at least with an R intereface). Thanks, Spencer Graves

Hello, I've looked in tools:::.install_packages for some sort of hook that would let packages developers point to further instructions after a package is installed. For example, some packages need to setup environment variables, ... Is there something I have missed ?

I am using the following script to make .jpg files. jpeg('plotx.jpg') ddat <-read.table("file",header=T) attach(ddat) tdat<-read.table("file1") plot(xx1,yy1,type='p',pch=1,col="blue",cex=0.2,xlim=c(0,3.5),ylim=c(-75,75)) points(tdat,col="green",pch=1,cex=0.2) dev.off() The problem is that I want the points to be very small;

Hi, I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way. I had a look on biops and EBImage (Bioconductor) but they are not automatic... Did you already use/know a such package ?

Hello everyone,  I'm working in a project to create an special analysis about visualization in some animals and its behaviour, through checking eye movement. The point is this is very important to get data from the image as a resume of what this animal sees. I think an RGB histogram like photoshop does, but I need to get the data from this histogram analysis and I was wondering about using R

Hi, on a lattice, I have binary 0/1 data. 1s are rare and may form clusters. I would like to know the size/length of largest cluster. Any help warmly welcome, Sylvain.

I have a bunch of jpg files that I need to count cells on. Some cells are green and some cells are red. Is there a function like locator that I could use to manually count the cells? I would like to be able to click on a cell, have it marked so I don't count it again and have a counter keep track. Locator comes close but I would only be able to count one colour at a time. Is there a way I

Hello, I need to do some basic statistics on raster images (tiff or png). I need only an advice where to start, which package is the most appropriate. My search attempts were without success, yet. Many thanks Tomas

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

Dear all I prepared some image processing routine which depended on package ReadImages. Basically I imported image to R, changed rgb to grayscale, normalised an image made some selections and changed to image by imagematrix. Recently I learned that this package was removed from CRAN and can not be used in R 3.0.0. What options I have now to import image to R, change it to grayscale, make some

I have a dataframe that has a header like so: class value1 value2 value3 class is a factor the actual values in the columns value1, value2 and value3 are 0-255, I wish to binarize these using biclust. I can do this like so: binarize(dataframe[,-1]) this will return a dataframe, but then I lose my first column class, so I thought I could combine it like so: dataframe <-

As far as I can tell, there are no facilities in the "base" R for image analysis. Is there any extension or package for R that implements image analysis? I'm thinking of features such as o Reading and writing image files, o displaying indexed or "true color" images, o resizing, cropping, etc, of images, o filters for manipulating images (smoothing, edge detection, etc) o

Hi R, Wanted to check if there are any packages available for getting the (x,y) data points of a graph or a plot, which is in the image format. Say, the plot could be a published report, and I want to get the points of the curve plotted.
