Hello ... In the name of aligning getBioC with reposTools, the 'relLevel' argument to getBioC() has been replaced with a boolean argument 'develOK', which defaults to FALSE. Users who wish to only receive release level software can either just use the default value or specify 'develOK=FALSE' instead of 'relLevel="release"'. Users who wish to access developmental packages, data packages, etc will need to specify 'develOK=TRUE'. As an example, to download the developmental versions of the 'affy' target in getBioC: getBioC("affy", develOK=TRUE) Or, to stay with all release level software: getBioC("affy") or getBioC("affy", develOK=FALSE) Please contact me with any questions, concerns or problems. Thanks -Jeff
