_D_e_s_c_r_i_p_t_i_o_n:

     This component provides qualitative diagnostic plots and
     quantitative measures for assessing general hybridization quality.
     All results are displayed in a HTML report. Agilent format only.

_U_s_a_g_e:

     agQuality(fnames = NULL, path = ".", organism = c("Mm", "Hs"),
     compBoxplot = TRUE, reference = NULL, controlMatrix = agcontrolCode,
     controlId = c("ProbeName"), output = FALSE, resdir = ".", dev= "png", DEBUG = FALSE,...)

_A_r_g_u_m_e_n_t_s:

  fnames: A "character" string naming the input files.

    path: A "character" string representing the data directory. By
          default this is set to the current working directory (".").

organism: A "character" string naming the organism genome printed on
          the array, either "Mm" or "Hs". By default, organism is set
          to "Mm". It is used to retrieve the corresponding reference
          tables.

compBoxplot: Logical. If set to 'FALSE', only qualitative diagnostic
          plots will be plotted. agQuality ouput will be limited to a
          diagnostic plot by file and a marrayRaw object.

reference: A matrix resulting from globalQuality, to be used as
          reference table to compare slides. If 'NULL', the default
          table corresponding to organism will be used. See details for
          more information.

controlMatrix: A character matrix of n by 2 columns. The first column
          contains a few regular expression of spotted probe sequences
          and the second column contains the corresponding control
          status. By default, is it set to be agcontrolCode.

controlId: Character string. Name of the column of the file used to
          define controls.

  output: Logical. If 'TRUE', normalized M values corresponding to the
          input Agilent files and quality measures are printed to a
          file.

  resdir: A "character" string representing the directory where the
          results will be saved. By default, this is set to the current
          working directory (".").

     dev: A "character" string naming the graphics device. This will
          take arguments "png", "jpeg" and "ps" only. By default, dev
          is set to "png".

   DEBUG: If 'TRUE', debug statements are printed.

     ...: Additional arguments.

_D_e_t_a_i_l_s:

     agQuality returns 2 plots for each Agilent files passed as
     argument. The first one is a qualitative diagnostic plot, a quick
     visual way to assess slide quality. The second one is a
     comparative boxplot: each quality control measure is compared to
     the range obtained for a database of 'good' slides used as
     reference. You can use your own set of references created using
     'globalQuality' passed in the arguments "reference", or use the
     reference QC values stored in the datasets 'MmReferenceDB' and
     'HsReferenceDB'. All results and quality scores are gathered in a
     HTML report. For more details about the QC measures and the plots,
     please refer to the online manual.

_V_a_l_u_e:

     A list of 2 elements: 

    mraw: A marrayRaw object created from the input files.

 quality: A matrix containing Quality Control measures for all slides.
