I just grabbed a new version of R, updated all my packages and I am running Mac OS 10.4.11. I installed ROOT, which seems to work, at least it opens up when I execute "root". I am very interested in getting xps to work. I retrieved the package xps_1.2.0. > library(xps) Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/Library/Frameworks/R.framework/ Resources/library/xps/libs/ppc/x ps.so': dlopen(/Library/Frameworks/R.framework/Resources/library/xps/libs/ ppc/xps.so, 6): no suitable i mage found. Did find: /Library/Frameworks/R.framework/Resources/library/xps/libs/ ppc/xps.so: mach-o, but wrong architecture Error: package/namespace load failed for 'xps' > I am not a great system admin I am afraid. Any suggestions appreciated. Tom

Dear Tom From the error message you get I assume that you have installed the newest version of ROOT. However, when downloading the binary version of xps from BioConductor you need to install root_v5.18.00, since this is the version installed on the BioConductor servers to build the binaries. However, for some reason BioConductor is not able to build the Tiger binary for ppc, thus the version xps_1.2.0 is pretty outdated (the newest version being xps_1.2.6). Since Tiger has everything to compile packages from source (in case you have installed the developer tools from the MacOS X system DVD) I would suggest to try: > source("http://bioconductor.org/biocLite.R") > install.packages("xps", type="source") This has the advantage that you can keep the newest version of ROOT installed on your Mac. Please let me know if this could solve your problem.
