similar to: tempfile problem

The other day I was working on an example which used tempfile() to create file for use by the graphics device. And while I love tempfile()---as it is portable and clever and the files get cleaned by R and all that---I noticed one missing feature I would like to see: beside a starting name pattern, and an optional directory, an 'file extension' argument would be nice to have. As e.g. in

Hi all, Yesterday, I had some problems reading JPG files in my tests. Turns out the problem was that Windows Ruby doesn't set it's Tempfile to work in binary mode. Since I deploy on Linux, that has never been a big problem, but now I'm working on some software that works with binary files exclusively. Anyway, I am making this fix available as a Rails plugin. The details can be

I''ve been facing a problem when generating a model (or controller, ...). I''m using rails 2.3.8 and ruby 1.8.7. Has anybody been facing anything like this? script/generate controller test /usr/lib/ruby/1.8/tempfile.rb:12: superclass mismatch for class Tempfile (TypeError) from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require''

I'm used to Debian-based distros which have a tempfile(1) utility for safely and sanely creating temporary files. There isn't a comperable utility for RHEL/CentOS systems. I've been exercising Google-fu looking for a good robust tempfile generation idiom, but haven't turned one up yet. Hence this appeal to the lazyweb. -- Dr. Ed Morbius, Chief Scientist / | Robot

Dear List: I'm posting this to provide a possible solution and to document to what appears to be an R limitation. The solution is more of a cheap hack that works for now. To provide a little background, I am looping through a dataframe and creating Sweave documents using data from each row in the dataframe. It appears that this technique is not scalable to large dataframes without making some

Hello, R version 2.4.1 (2006-12-18) i386-pc-mingw32 Calling serialize() with a NULL connection serializes it to a raw vector. However, when the object to be serialized is large, it takes a very long time: > system.time( serialize(matrix(0, 1000, 1000), NULL) ) [1] 38.25 40.73 81.54 NA NA > system.time( serialize(matrix(0, 2000, 2000), NULL) ) [1] 609.72 664.75 1318.57 NA

Dear List: I am encountering an error that I can't resolve. I'm looping through rows of a dataframe to generate individual tex files using Sweave. At random points along the way, I encounter the following error Error in file() : cannot find unused tempfile name At which point Sweave halts. There isn't a logical pattern that I can identify in terms of why the program stops at

I have three (out of 90) machines with the error: cannot generate tempfile `/tmp/puppet.30616.9'' I have plenty of disk and plenty of inodes.

I came up with a patch to fix the problem of IO Errors caused by excluded files as did Eugene V. Chupriyanov below. Is there a chance that this change will show up in a future version of rsync? Is there a reason that we should not ignore IO errors when copy_links is off? Just want to make sure that I'm not missing something here that may corrupt my syncs.... Here's the version that

Hello, I need to be able to write a temporary file for use during the request only. Locally I can use the following successfully: tempfile = File.open(a.original_filename,''w'') tempfile.write_nonblock(a.body) paperclip stuff........ tempfile.close That works great, but not on Heroku... How can I do the above with Heroku''s restrictions:

I am looking for a way to upload a file to Rails 3 app, but without generating a temp file. Googling the issue gave me some insight in how the file upload works. As I understand Rails creates a temp file when the file size is larger than 20kb. Is there a way to change this limit and avoid the temp file generation? Another solution I was looking in was creating a Rack App and so avoid the file

Hi all, I've been writing a package and I've run into a problem that I'm unsure how to solve. I am looking to pass a C++ class object to R so that it may be passed back to another C++ function later on to be used. I'm quite new to R and this is my first time writing a package, so I hope you can bear with me. The following is how I create the class and use

When I mistakenly use file.copy() with a directory for the 'from' argument and a non-directory for the 'to' and overwrite=TRUE, file.copy returns FALSE, meaning it could not do the copying. However, it also replaces the 'to' file with a zero-length file. dir.create( fromDir <- tempfile() ) cat(file = toFile <- tempfile(), "existing file\n")
