It was recommended that I post this problem to the mailing list. I am unable to get affy to work, e.g. the library loads into R, but the functions don't seem to work. I was hoping someone may have seen this problem before and may have a solution. I am working in the correct working directory. I am using version v2.0.1 of R with the default Bioconductor package installed. Current package of Affy is 1.5.8. I am using Mac OS X 10.3.7 and running X11 (X11 1.0 - XFree86 4.3.0). This is a shared environment and all packages were installed in the top library, not in the User library. On prompt: > load("/nnn/nnn/nnn/timecourse.RData") > library(affy) Loading required package: Biobase Loading required package: tools Loading required package: reposTools > ReadAffy(widget=T) Error: couldn't find function "ReadAffy" > ReadAffy() Error: couldn't find function "ReadAffy" > pData(eset) Error: couldn't find function "pData" I've also attempted to "start from scratch" from the original .cel files and get the same type of error message that the function couldn't be found. I have checked to ensure that affy is installed and loaded, and based on the Package Manager, it is . I've also tried using limma (v1.8.10), and had no problems, other than I can't read in the eset. > packageDescription("limma", field="Version") [1] "1.8.10" > packageDescription("affy", field="Version") [1] "1.5.8" > version _ platform powerpc-apple-darwin6.8 arch powerpc os darwin6.8 system powerpc, darwin6.8 status major 2 minor 0.1 year 2004 month 11 day 15 language R Thanks for the assistance.

I > attempted again to try the ReadAffy function and it failed. > Hmm, this seems really odd. So a whole bunch of questions in the hopes that one of them sheds some light on what your problem is. Basically, if the library is attached and the function is listed, it is there (or ought to be). Please show the entire transcript of you session (in answering the questions below, not just the part you want to) [possibly skipping to the end, as I now suspect that you do not have enough system software installed - we should think about how to find that out more automatically] If you just type ReadAffy, what happens? what if you type the name of one of the other functions (in any of the packages)? what is .libPaths() reporting? >> If not, then the installation is not correct.

My entire session follows. The previous .RData session was performed on another computer while I was learning the basics of R and affy. Prior to loading "timecourse.Rdata", I started X11 and changed the working directory to the proper working directory with my data in it. > load("/xxx/xxx/ArrayAnalysis/timecourse.RData") > ls() [1] "PMA.Calls" "Pearson.cor" "adjp" "coc.phenodata" [5] "deg" "eset" "mynova.full" "procs" [9] "raw" "raw.pvalue" "res" "timecourse" [13] "x" > library(affy) Loading required package: Biobase Loading required package: tools Loading required package: reposTools ## Note here that everything loaded just fine, as far as I can tell.

I selected the .cel files I wanted use (the ones that made up the eset above) and then after selecting them, the error message popped up. > packageDescription("affy", field="Version") [1] "1.5.8" > version _ platform powerpc-apple-darwin6.8 arch powerpc os darwin6.8 system powerpc, darwin6.8 status major 2 minor 0.1 year 2004 month 11 day 15 language R ## This search demonstrates the packages that are active at this point in the session. > search() [1] ".GlobalEnv" "package:tkWidgets" "package:DynDoc" [4] "package:widgetTools" "package:tcltk" "package:affy" [7] "package:reposTools" "package:Biobase" "package:tools" [10] "package:methods" "package:stats" "package:graphics" [13] "package:grDevices" "package:utils" "package:datasets" [16] "Autoloads" "package:base" ## I wanted to demonstrate the functions and files associated with affy in my library.

I suspect that there must be something wrong with either the install or that the calls used by affy became corrupt either at the source or during the install. I should offer one caveat here. I have experienced this problem with affy ever since I first installed it two weeks ago. I have attempted to do re-installs of the affy package and clean installs of R. Nothing has remedied this issue. And when I say clean install, I mean I have crawled through the system and deleted everything from the libraries to the install .pkg that OsX likes to hide. I also deleted preferences. I also check system level and user level libraries to ensure I got everything that was installed prior to the clean install. If I try to do a reinstall over the current package I get the following session: trying URL `http://www.bioconductor.org/src/contrib/PACKAGES' Content type `text/plain' length 46409 bytes opened URL ================================================== downloaded 45Kb trying URL `http://www.bioconductor.org/src/contrib/PACKAGES' Content type `text/plain' length 46409 bytes opened URL ================================================== downloaded 45Kb trying URL `http://www.bioconductor.org/src/contrib/affy_1.5.8.tar.gz' Content type `application/x-tar' length 1076622 bytes opened URL ================================================== downloaded 1051Kb * Installing *source* package 'affy' ... creating cache ./config.cache checking how to run the C preprocessor... /lib/cpp checking for main in -lz... no updating cache ./config.cache creating ./config.status creating src/Makevars ** libs /Library/Frameworks/R.framework/Resources/bin/SHLIB: line 1: make: command not found ** Removing '/Library/Frameworks/R.framework/Versions/2.0.1/Resources/library/affy ' ** Restoring previous '/Library/Frameworks/R.framework/Versions/2.0.1/Resources/library/affy ' ERROR: compilation failed for package 'affy' > Delete downloaded files (y/N)? y ##I deleted the file this time, but have and haven't at other times. > It is at this point, I toss up my hands and beg for help.

So Stefano seems to have identified your problem. You either need to get precompiled OS X binaries, or install enough of the developer tools to compile the source packages from Bioconductor. The problems that you are having seem to be due to the fact that many functions did not build correctly since you don't have a C compiler. The Aqua version of R that you have installed should have some sort of menu item that you can use to get the packages, and I think you need to use that. I'm afraid I don't use it myself, so I don't know just how it works. Robert On Jan 25, 2005, at 1:43 PM, Chad Wayne wrote: > My entire session follows.
