Web26 sep. 2024 · The types of comparisons you can make will depend on the design of your study. In the following example we will use the raw counts of differentially expressed (DE) genes to compare the following Daphnia genotypes. WebA list of two dataframes : logFC and P_Value. The first one contains the logFC values of all the comparisons (one column for one comparison), the second one contains the pvalue of all the comparisons (one column for one comparison). The names of the columns for those two dataframes are identical and correspond to the description of the comparison.
