Dear BioC, I have a problem when I use the function normalize.loess o a matrix of data(24136, 28). the error is the following. normalize.loess(matrix) Error in vector("double", length) : vector size cannot be NA it is strange, because it do not happen if I subindex the matrix for less genes. I checked if the matrix is numeric, and it is so. then I wonder what is the problem. thanks -- Claudio ------------------------------------------------------ Passa a Infostrada.

Dear Claudio, please send a script that allows us to reproduce your error, together with the output of sessionInfo(). Without that information, it is very difficult to give you any reply (you didn't even say which package you're using).
