Re: [R] rimage package broken with fedora upgrade

Thanks to Jonathan and Oleg for their suggestions/comments. Their responses are added at the end of this email.

I tried Oleg's suggestion of giving me write permissions on /usr/lib/R/library. This didn't seem to work (I tried various combinations of changing permissions and ownership but nothing worked). Anyway, before changing permissions the library would not work when R was fired up as root. I am by no means a linux/unix expert and maybe there is some method of giving me write permissions that would have solved the problem.

Jonathan was right that his was essentially a different problem. I already had fftw2 installed.

My (heavy-handed) solution was to bite the bullet and re-install fedora core 6 from scratch. (Apparently the upgrade from fc3 does not work as well as back up + fresh install.) After running yum update, I then installed R by clicking the relevant R RPM in CRAN. I subsequently installed fftw2 and fftw2-devel (using "yum install package_name") (the development package is needed) and installed rimage using install.packages("rimage") within R and everything is now fine. Note that it is also necessary to install libjpeg and libjpeg-devel if you do not already have it.

I hope that this helps others that want

I am looking forward to playing with Oleg's EBimage package.

Thanks again and Happy New Year to all!

As you use a global R installation, try giving yourself write permissions in /usr/lib/R/library, this might help. Otherwise, try installing R from source in your home or elsewhere where you have all write permissions and check it again. Anyway, I wanted also to advertise my package because you use rimage: The difference is - it supports up to 95 image formats and implements many image processing methods. In fact you can combine this with functions from rimage. If interested, go for a development version above and it works on Fedora 6 Zod and 2.4.1 - did try just today.
