[R] To convert MAList to ExpressionSet using R package 'convert'

I am 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 got 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 means and how to settle this problem.

Please, help me.

I've just resolved the problem.

The 'targets' format in the MAList file was omitted.

After adding the 'targets', the function 'as' worked.

Thank you.

Could you edit the title to mark it [CLOSED] ?
