I'm currently working on a meta-analysis of transcriptomics datasets that have published recently.
I want to convert MAList to ExpressionSet using R package 'convert'.
However, I had an error message as following.
> eSet <- as(MA, "ExpressionSet")
Error in `rownames<-`(`*tmp*`, value = c("10A_12477149", "10B_12477150", :
attempt to set 'rownames' on an object with no dimensions
I don't know what the message indicates and how to settle this problem.
