I recently upgraded to R 2.4.1 and ran biocLite to install the Bioconductor packages. This installs version 2.9.17 of limma. I also have my old version of R (2.1.1 which has version 2.3.3 of limma).
When I run
fit.O2<-lmFit(MA[isGene,], design.O2, weights=w)
in R 2.4.1 I get the error message
Error in asMatrixWeights(weights, dim(M)) :
weights is of unexpected shape
but this works fine in R 2.1.1
This is how I made my weights matrix:
# and then set anything with a weight of 0.1 to a value of 0
the last four lines are using information from the spot types file.
Can anyone tell me why this is happening? I really need the spot weights to be used.
