Hello, I have installed limma GUI and I'm trying to repeat some analysis that I did before with limma. When I try to Normalize Within arrays using the composite method (I have control spots called "control" in the Spot types file) I receive the message: "Error in library, character only=TRUE, logical=TRUE, warn.conflicts=warn.conflicts, : 'sma' is not a valid package--installed < 2.0.0?" To be sure that this problem is not due to my data I have followed the swirl tutorial, and whenever I try to use "Within slides normalization" I obtain the same message. Assuming that the problem may be due to an outdated 'sma' version I have looked for the new one in Bioconductor's web but I have been unable to find it Any ideas?
