I'm tryng to use loess normalization function based on externals 
controls (like MSP) as in Yang et al.; 2002 paper. I work with 
bioconductor marrayNorm package. I identified my controls in the 
maControls structure of marrayLayout as a vector of 0 and 1.  Is 
someone still use it ? for the moment I just have ...

test <- maNormMain(manip.raw, f.loc = list(maNormLoess(x="maA", 
y="maM", z="maControls",subset=TRUE)))

but answer is Error in simpleLoess(y, x, w, span, degree, parametric, 
drop.square, normalize,  :	invalid `x'
