I want to perform meta-analysis of gene expression data by using 'MetaDE'

MetaDE.pvalue(x,meta.method='minP')

Where x is a list of matrix containing p-values with corresponding genes.

My data looks like 

           P.value   P.value.1
1007_s_at 0.000218932 0.000218932
1053_at   0.017000453 0.017000453
117_at    0.066864977 0.066864977
121_at    0.000218932 0.000218932
1255_g_at 0.320830091 0.320830091
1294_at   0.001602361 0.001602361

 

For The above code it give 

Error in matrix(NA, nrow(x$p), nm) : non-numeric matrix extent

I am not sure what is going wrong. Help appreciated. Thanks

Sorry For the late reply    #(maybe my response will be useful for for someone else)

Your x have to be list object with components : 

- p :  list of p values for each dataset.

so add the line below : 

x<-list(p=x)  

and then 

MetaDE.pvalue(x,meta.method='minP')

Cheers
