[BioC] Error creating marrayInfo

[Jean Yee Hwa Yang]

Hi David,

Sorry, this is a bug in marray* packages.  There is a fix if you download
the marrayClasses 1.2.1 (developmental version).  
http://www.bioconductor.org/repository/devel/package/html/marrayClasses.html
I am in process of putting the bug fix on the release version.

Cheers

Jean
