Error in camera function in limma

Question

[mehmeteahsen]

Hi,

I have done a differential expression analysis using limma. When I try the camera analysis

dummy_out=camera(voom_data,all_signatures_for_camera,design,contrast.matrix1)

I get the error

Error in U[iset, , drop = FALSE] : no 'dimnames' attribute for array

Here the voom_data is the voom output, design is what I use the design matrix in voom. all_signatures_for_camera is a list of 18 gene sets.

What is causing the error?

Thanks
