Dear Bioconductor users,

 

I want to analyze a set of spotted arrays with an irregular spotting design,
so “avereps” seems to be appropriate to get averaged expression values for
each transcript. However, applying this to my data

 

> dim(my.arrays)

[1] 11520    18

> is(my.arrays)

[1] "MAList"          "list"            "LargeDataObject" "vector"        

 

produces the following error:

 

> averaged<-avereps(my.arrays)

Error in avereps.default(x$M, ID = ID) : 

  (subscript) logical subscript too long

 

Can anyone give me a hint what’s going wrong here?

Thanks a lot in advance,

Claus-Jürgen Scholz
