_I_s_o_P_l_o_t

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

     Plot of the data points and the sample means at each dose

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

     IsoPlot(x, y, type=c("continuous", "ordinal"), add.curve = FALSE)

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

       x: indicates the dose levels 

       y: is the gene expression for one gene 

    type: specifies the dose levels to '"continuous"' or '"ordinal"'.
          The default is '"continous"'.

add.curve: specifies whether a fitted isotonic regression curve with a
          likely direction is added or not. The default is 'FALSE'.

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

     Plot of the data points, the sample means for each dose (either as
     continuous or ordinal), and a fitted isotonic regression curve
     (optional) is produced.

_N_o_t_e:

     This function produces a plot for a single gene.

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

     Lin et al.

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

       x <- c(rep(1,3), rep(2,3), rep(3,3), rep(4,3))
       y <- c(rnorm(3,1,1), rnorm(3,2,1), rnorm(3,3,1), rnorm(3,4,1))
       IsoPlot(x, y)
       IsoPlot(x, y, type="ordinal", add.curve=TRUE)
