     Affymetrix define a series of QC parameters for their arrays. Many
     of these rely on specific probeset that differ between arrays and
     are used to calculate things like 3'/5' ratios. See 'qc.affy' for
     more details. These functions are used to set up the appropriate
     QC environment for the specified array. This is done by loading a
     configuration file, either from the packages data directory, or
     from the specified path. See the package vignette for details of
     the config file's syntax.

_U_s_a_g_e:

      setQCEnvironment(array,path=NULL)

_A_r_g_u_m_e_n_t_s:

   array: This should be the 'clean' cdf name of the array as generated
          by 'cleancdfname' in the affy package.

    path: Path to the file. By default, checks the package's own data
          directory - only needed if a defininition file is being
          specified manually, as described in the vignette.

_D_e_t_a_i_l_s:

     The usual way to get the 'clean' cdfname is as follows:
     'cleancdfname(cdfName(eset))', where 'eset' is an 'AffyBatch'
     object.

_V_a_l_u_e:

     none.
