_D_e_s_c_r_i_p_t_i_o_n:

     Function to return the intensity of beads on an array with a
     certain ProbeID.

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

     getProbeIntensities(BLData, ProbeIDs, array, log = TRUE)

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

  BLData: BeadLevelList object containing bead level data

ProbeIDs: numeric value for the ProbeID we want values for

   array: numeric value giving the array we want to find values on

     log: if TRUE then log2-transformed data will be returned

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

     The function simply looks up the BLData$R values for beads whose
     BLData$ProbeID matches the given 'ProbeID'. A log2 transform is
     then applied if  specified.

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

     vector of numeric values corresponding to the intensity of all
     beads on the array with the specified 'ProbeID'

_A_u_t_h_o_r(_s):

_E_x_a_m_p_l_e_s:

     data(BLData)

     getProbeIntensities(BLData, 2, 1)

     ##To return log2 data use

     getProbeIntensities(BLData, 2, 1, log=FALSE)

     #ProbeID 4279 is a housekeeping control in our experiment

     getProbeIntensities(BLData, 4279, 1)
