one more question about songbird, especially the formula and entering ordered values. I have timeseries experiment with timepoints 1 to 6. I managed to get songbird to wok this way but I am not 100 % certain about the results.
If I enter C(sample_time, Diff, levels=['S_1, ‘S_2’, ‘S_3’, ‘S_4’, ‘S_5’, ‘S_6’]) it will give me 5 columns named S1 S2 S3 S4 and S5. Are the differentials in the column S1: S2 compared to S1, column S2 would be S3 compared to S2 or how should they be read?
My background is that Im using the differentials to make a heatmap and would thus like to display a timeseries from timepoint S1 to timepoint S6.
ANy help would be highly appreciated!
