Default is absolute. glen: The length of the gene line plotted _D_e_t_a_i_l_s: It is important to call the function 'cPlot()' first. This function will then search for the specific locations of the probes desired, which are contained within the 'plotChroms' instance of a 'chromLocation' class. It will then pass these on to the plotting routine to highlight the desired locations. NOTE: It is important that 'plotChroms', 'scale' and 'glen' parameters are the same as used for 'cPlot()'. _A_u_t_h_o_r(_s): Jeff Gentry _S_e_e _A_l_s_o: 'cPlot', 'chromLocation-class' _E_x_a_m_p_l_e_s: if(match("hgu95av2", .packages(all = TRUE), nomatch=0)) { library("hgu95av2") z <- buildChromLocation("hgu95av2") cPlot(z) probes <- c("266_s_at", "31411_at", "610_at", "failExample") cColor(probes, "red", z) probes2 <- c("960_g_at", "41807_at", "931_at", "39032_at") cColor(probes2, "blue", z) } else print("Need hgu95av2 data package for the example")
