Dear Adeline,

the problem you report is due to the fact you don't have the required  
annotation package installed.

Because the example you downloaded is not an expression experiment, my  
suggestion is to use the one shown on the vignette (given that you  
didn't provide a sessionInfo(), I assume you're running R 2.9.2):

http://www.bioconductor.org/packages/release/bioc/vignettes/oligo/inst/doc/oligoNimblegenExpression.pdf

In order to run the analysis described on the aforementioned PDF, you  
will mainly need the following packages:

- pd.hg18.60mer.expr
- maqcExpression4plex

pd.hg18.60mer.expr is the annotation package needed to read in the XYS  
files (produced by NimbleGen) provided by maqcExpression4plex. The "pd  
package", as described by the vignette, was built using the  
pdInfoBuilder package.

So, to run the vignette example, my suggestion is (under R 2.9.2 and  
the latest BioC):

## start
pkgs = c("oligo", "pd.hg18.60mer.expr", "maqcExpression4plex",  
"genefilter", "limma", "RColorBrewer")
source("http://www.bioconductor.org/biocLite.R")
biocLite(pkgs)
## end

Once the packages are installed, you will be able to run that  
particular example.

When working with your own experiment, you will need to create the  
annotation package for your data. To do that, you will need to use the  
pdInfoBuilder package and you can use its vignette "Building  
Annotation Packages with pdInfoBuilder for Use with the oligo  
Package" (in particular, Section 9) as a reference.

Anyways, to create your annotation package (for NimbleGen Expression),  
you will need:

- NDF file
- XYS file (one suffices, as it will be ued as templates)
- pdInfoBuilder package

Once everything is in place, you need (replace capital letters by the  
appropriate values):

seed <- new("NgsExpressionPDInfoPkgSeed",
                        ndfFile=YOURNDF,  xysFile=YOURXYS,
                        author=YOU, email=EMAIL,
                        biocViews="AnnotationData",
                       genomebuild=BUILD, organism=ORG,
                       species=SP, url=URL)
makePdInfoPackage(seed, destDir = ".")

This will create the package under  your current directory. After the  
package structure is created, you need to build and install it (using  
the regular R CMD build and R CMD INSTALL).

Please let me know how this works for you,

With best wishes,

b
