Hi I am attempting to use gcRMA on HuEx-1_0-st-v2 CEL files.

I have the correct data structure, files (CDF, Probeset etc).

Using a workflow similar to this;


I am able to run RMA fine. However, substitituting for the gcRMA
function found here,


Causes the following error:

The following object(s) are masked from 'package:matrixStats':

    anyMissing, rowMedians

Error in if (from == to) rep.int(from, length.out) else
as.vector(c(from,  :
  missing value where TRUE/FALSE needed
20110407 14:18:14|  Array #1 of 12...done
20110407 14:18:14| Adjusting 12 arrays...done
20110407 14:18:14|Background correcting data set...done

Any ideas, suggestions on how to fix this would be greatly
