Hi, everyone, I ran the test case in "Introduction to the Bioconductor marrayInput package first. When I ran the session in (read.marrayRaw) I got the following error messages. Other sessions work well. The functions and errors are labled with blue and red respectively. >mraw <- read.Spot(path = datadir, layout = galinfo$layout, gnames = galinfo$gnames, target = swirlTargets) Error in file(con, "r") : unable to open...

..."formula"), plot.ma) where marrayNorm is a class defined in the marray package. After building and installing my package, I get the following warnings when I load my package (with library(maVis)): Warning messages: 1: In the method signature for function "plot", class "marrayRaw" has no current definition in: matchSignature(signature, fdef, where) 2: In the method signature for function "plot", class "marrayRaw" has no current definition in: matchSignature(signature, fdef, where) (but everything appears to work ok regardless). I have tried requir...

...ther than by the lower-left cell... In many cases, it can be usefull to have a representation of the data spatialy corresponding to a real support, as it is the case with the function image(marray) from Bioconductor packages, which fills the graphical matrix by row from upper-left, but just handles marrayRaw or marrayNorm objects. Of course, I could reorder the matrix, but it's heavier than with an already available function if it exists... Thanks a lot for help BUHARD Olivier
