Dear everyone I am a bit of a computer imbecile and are having problems with R. I am using R in my research project to do chi-square tests on data imported from excel . However I have som missing data in one of my variables (columns) and I need R to "exclude" these and make chi-square test on the data that I have. I use a formula to make 2x2 tables which is: data <-

Dear list, I'm using the function "movie3d" in the package "rgl" to create a .gif animation of a 3d graphic. The program "ImageMagik" is working properly, R packages are working, basic examples available in the manual also working fine. Problem Solved: when I tried to create more complex movies, i.e. combining different views and zooming, the R-console crashed

I''m looking at Dragonfly, which seems to offer what I''m looking for in this area: the ability to upload an image, then later request that image at a different geometry, and either get a cached copy of that resized image, or create and cache that image. Can anyone point me to alternatives? Is this something that can be added to Paperclip? I''ve only ever used

Programs with special uncommon file formats (not jpg) often register a shell extension in Explorer that offers thumbnails for these files (since the files otherwise wouldn't have previews). When I trigger in a Wine application (eg. SketchUp) the File Open dialog, I can see previews of the files (skp files) in the preview panel. This means the shell extension does work in Wine. The Shell

Hi, 1. How to resize an image uploaded by a web form before saving it to the disk? (i need all uploaded images to have similar size) 2. How to create thumbnails? Is it enough if i specify small size of the image in html or would the image look horrible? Can i do it somehow in ''realtime'' using javascript? Or is it best to create thumbnail as a separate file? 3. How to get

Hello, Recently attachment_fu stopped resizing images for me. I''m puzzled because before today it was resizing them and I don''t know what''s changed. Here''s my code: class Product < ActiveRecord::Base has_attachment :content_type => :image, :storage => :file_system, :max_size => 18.megabytes,

I''d like to implement a system in a Rails app where I allow the user to upload an image file, and then the app takes that image and manipulates it, saving a thumbnail, small, and original size version of the file to the server. How would I go about doing that? Thanks, Jeff -- Posted via http://www.ruby-forum.com/.

Im using a customs processor to run ffmpeg on a video to create a thumbnail. So far so good.

Hi, I''m brand new to RMagick (and pretty new to Rails for that matter!). Right now, site owners are allowed to upload product and ingredient photos to the website. Everything works great, ingredients are sized down and proportioned correctly...the problem is that the resulting images are so blurry! So I''ve been doing some research and it looks like Paperclip::Processor may be the

I know that Zed has made mention of the fact that using RMagick with mongrel and rails is a bad thing. I''m currently using FlexImage (which in turn uses RMagick) on my application and really haven''t had too many problems. We get a restart for memory usage every 8-10 hours on one mongrel of twelve running, but I''m not sure if that''s an RMagick issue. Either way,

I''m working on an image system that does rescaling and effects on demand, rather than on upload. The uploads are stored as master files, and resized images are generated, cached and returned by a controller, using a request similar to this: /images/21/150x100/filename.jpg (where 21 is the image id) I also have various filters implemented, adding the concept of filter sets (which is

Hi, I am using rmagick to resize a copy of uploaded images and display the copy as a thumbnail. Once the upload is processed it redirects the user to a page that should display the thumbnail to the user. The problem is that the rmagick resize function seems to keep going in the background after handing the new images url (and control) back to rails, which then happily renders the page with
