_D_e_s_c_r_i_p_t_i_o_n:

     This function converts an 'AffyBatch' into an 'PLMset' by fitting
     a multichip model. In particular we concentrate on the RMA model.

_U_s_a_g_e:

     rmaPLM(object,subset=NULL,normalize=TRUE,background=TRUE,background.method="RMA.2",normalize.method="quantile",background.param = list(),normalize.param=list(),output.param=list(),model.param=list(),verbosity.level=0)

_A_r_g_u_m_e_n_t_s:

  object: an 'AffyBatch'

  subset: a vector with the names of probesets to be used. If NULL then
          all probesets are used.

normalize: logical value. If 'TRUE' normalize data using quantile
          normalization

background: logical value. If 'TRUE' background correct using RMA
          background correction

background.method: name of background method to use.

normalize.method: name of normalization method to use.

background.param: A list of parameters for background routines

normalize.param: A list of parameters for normalization routines

output.param: A list of parameters controlling optional output from the
          routine.

model.param: A list of parameters controlling model procedure

verbosity.level: An integer specifying how much to print out. Higher
          values indicate more verbose. A value of 0 will print nothing

_D_e_t_a_i_l_s:

     This function fits the RMA as a Probe Level Linear models to all
     the probesets in an 'AffyBatch'.

_V_a_l_u_e:

     An 'PLMset'
