Your PDF problems indicate a broken viewer. How were you viewing PDF?
You have also not told us how you view PNG, but you would expect anti-aliased output to be blurry when viewed at 100% (or more). You need to be careful not to have anti-aliasing turned on in the viewer as well as in the file producer. Note that R does give you lots of options to tune the output to your intended use of it, so you have no cause to complain if you use an inappropriate set.
Do remember that you cannot say 'the graphical output is blurry': it is just a binary file. Far too often, useRs blame R for issues in the viewers they use.

On my current home system, I am getting undesirable output from graphical devices such as png() and pdf(). The graphical output is blurry. I haven't experienced the problem on other systems. As you will see from the attached text file (more information on this file below), the problem does not occur when type='Xlib' is forced. The blurriness is more severe with bitmap output (yes, I am viewing the bitmap files at 100%), but occurs with pdf output as well. Software details: Fedora 10, with at least the following packages: -- R, R-core, R-devel -- cairo, cairo-devel -- pixman, pixman-devel -- libpng, libpng-devel -- poppler Everything is "current" and updated via Fedora's repository. R was installed via Fedora's repository. I've attached some commands and output in a text file. This file includes: (1) hardware information (2) information about my R installation (3) code for simple R graphics, with comments re output, plus URLs for the corresponding graphical output Any advice would be really appreciated.
