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. _N_o_t_e: _A_u_t_h_o_r(_s): Crispin J Miller _R_e_f_e_r_e_n_c_e_s: http://bioinformatics.picr.man.ac.uk/ _S_e_e _A_l_s_o: 'qc' _E_x_a_m_p_l_e_s: setQCEnvironment("hgu133plus2cdf") setQCEnvironment(cleancdfname("HG-U133_Plus_2"))
