_D_e_s_c_r_i_p_t_i_o_n:

     Reads the specified file, which defines phenotypic data for a set
     of .CEL files. Reads the specified files into an 'AffyBatch'
     object and then creates a 'phenoData' object, defining the
     experimental factors  for those chips.

_U_s_a_g_e:

     read.affy(covdesc = "covdesc",path=".", ...)

_A_r_g_u_m_e_n_t_s:

 covdesc: A white space delimited file suitable for reading as a
          'data.frame'. The first column (with no column name)  
          contains the names(or paths to) the .CEL files to read.
          Remaining columns (with names) represent experimental factors
          for each chip. these become elements of the 'phenoData'
          object. 

     ...: extra functions to pass on to 'ReadAffy' 

    path: The path to prefix the filenames with before calling
          'ReadAffy'
