When I try to run the following line of code: cln.fit2 <- contrasts.fit(cln.fit, cln.cm) where cln.fit comes from: cln.fit <- lmFit(colon$M, cln.mm) where colon is a limma object and cln.mm is the model matrix. also cln.cm is the contrast matrix from: cln.cm <- makeContrasts(MSLiver-MSLung, MSLiver-MSLiverLung, MSLung-MSLiverLung, levels=cln.mm) I get the error: Error in o %*% RUC^2 : non-conformable arguments Can anyone tell me what I'm doing wrong?

We have seen this error message previously when the design matrix was singular and people attempted to take contrasts of non-estimable coefficients. There was a fix introduced in limma 1.7.5 to warn about non-singular design matrices and to catch this problem in contrasts.fit(). Try updating limma and see if the above turns out to be the problem. It is easiest to update limma directly from CRAN, just typing > install.packages("limma") should do it.

I updated my version and still get the same error. Here is the model matrix if that helps: cln.mm A B C D E F H I J 1 0 0 0 1 0 1 0 0 0 2 0 0 0 1 1 0 0 0 0 3 1 0 0 0 0 1 0 0 0 4 0 0 1 0 0 0 0 1 0 5 0 0 1 0 0 0 0 1 0 6 0 0 0 1 0 1 0 0 0 7 1 0 0 0 1 0 0 0 0 8 0 0 0 1 1 0 0 0 0 9 1 0 0 0 0 0 1 0 0 10 0 0 1 0 0 0 0 1 0 11 1 0 0 0 1 0 0 0 0 12 0 1 0 0 0 0 0 1 0 13 0 1 0 0 0 1 0 0 0 14 1 0 0 0 1 0 0 0 0 15 1 0 0 0 0 0 0 1 0 16 0 0 1 0 0 0 0 1 0 17 0 0 0 1 1 0 0 0 0 18 1 0 0 0 0 0 1 0 0 19 1 0 0 0 0 0 1 0 0 20 0 0 0 1 1 0 0 0 0 21 1 0 0 0 1 0 0 0 0 22 0 0 0 1 1 0 0 0 0 23 0 0 0 1 0 0 1 0 0 24 0 0 0 1 0 0 1 0 0 25 0 0 1 0 0 0 0 1 0 26 0 0 0 1 0 0 1 0 0 27 1 0 0 0 1 0 0 0 0 28 1 0 0 0 0 0 1 0 0 29 0 0 1 0 0 0 0 1 0 30 1 0 0 0 0 0 1 0 0 110 0 0 1 0 1 0 0 0 1 210 0 0 1 0 1 0 0 0 1 31 1 0 0 0 0 1 0 0 1 41 1 0 0 0 0 0 0 1 1 51 1 0 0 0 0 0 0 1 1 61 0 1 0 0 0 1 0 0 1 71 0 0 0 1 0 0 0 1 1 81 1 0 0 0 1 0 0 0 1 91 0 1 0 0 0 0 1 0 1 101 1 0 0 0 0 0 0 1 1 111 1 0 0 0 0 1 0 0 1 121 0 1 0 0 1 0 0 0 1 131 0 1 0 0 0 1 0 0 1 141 1 0 0 0 1 0 0 0 1 151 0 1 0 0 1 0 0 0 1 161 0 1 0 0 0 0 1 0 1 171 1 0 0 0 1 0 0 0 1 181 0 1 0 0 1 0 0 0 1 191 0 1 0 0 1 0 0 0 1 201 1 0 0 0 0 0 0 1 1 211 0 1 0 0 0 1 0 0 1 221 0 1 0 0 0 0 0 1 1 231 1 0 0 0 0 0 0 1 1 cln.cm <- makeContrasts(A-B, A-C, B-C, levels=cln.mm) cln.fit2 <- contrasts.fit(cln.fit, cln.cm) I'm now running limma version 1.7.7 Thanks for any help you can give.

You design matrix singular. If you run lmFit() it will warn you that coefficient I is non-estimable. Gordon > I updated my version and still get the same error.
