On a headless Linux server running R 2.9.2 I would like to enable support for cairo, but capabilities("cairo") keeps on giving me FALSE. Is it possible what I am trying to do or can this only be achieved at R build time? I do not have administrative rights on this server. After compiling cairo-1.8.10 and its dependencies from source in my home directory, I finally managed to install the Cairo package (capital C). Although capabilities("cairo") still gives me FALSE, I am now able to produce graphics. Apart from convenience, is there any difference between using built-in support for cairo or using the Cairo package? Carsten
