Hi, 
I'm the first to test this package and I have some problems.

1.I have installed perl on windows ( vista)..

2 In my directory QC : I've ONE file : mydata_Avg.txt , files generated by 
Genome Studio with label as indicated in vignette :
 - Index
- TargetID
- <Sn>.AVG Beta
....

3 Then , I have tested my code :
#biocLite("amap")                          
library(amap)

#biocLite("methylumi")                          
library(methylumi)

#biocLite("HumMeth27QCReport")                          
library(HumMeth27QCReport)


Dir = "F:/QC" 
Dir2 ="C:/Program Files/R/R-2.12.0/library/HumMeth27QCReport/DemoData"
HumMeth27QCReport(Dir2)

4 First OUT:
> HumMeth27QCReport(Dir)
Erreur dans file(file, "rt") : argument 'description' incorrect
> QCRep(Dir)
Erreur dans file(file, "rt") : argument 'description' incorrect

5 I test with Dir2 with DEMODATA
> HumMeth27QCReport(Dir2)
Erreur dans file(file, ifelse(append, "a", "w")) : 
  impossible d'ouvrir la connexion
De plus : Message d'avis :
In file(file, ifelse(append, "a", "w")) :
  impossible d'ouvrir le fichier 'sample.txt' : Permission denied


QUESTIONS: 
Have I forget a file  which describe my experiment?
Have I misunderstanding in the documentation of HumMeth27QC packages?

Thanks for your help
