I am trying to quantile normalize my Agilent MiRNA array data.

I have been following some instructions that should have worked:

i have performed > read.table(), then corrected my data for Negative  
values then >Log2() transformed.

My instructions were to then load the (affy) package then do:

 > normalize.quantiles(as.matrix(log2_file_name))

but there does not seem to be a normalize.quantiles() function.

I am running R 2.8.0 with affy_1.20.0.  Was this function from a  
previous version of affy or am i doing something stupid
