Description

This function explores the robustness of analysis with sequencing depth altering

Usage

1
exploreRob(df_d, lbl, f_vect)

Arguments

df_d

a dataframe containing the dataset to explore with 3 columns : label, f ratio, value to compare (e.g. number of differentially expressed genes)

lbl

a character string specifing the label for which the analysis should be run

f_vect

A numeric vector containing the values of f for which the analysis should be run

Details

exploreRob function to explore the robustness of the analysis with altering of sequencing depth. It runs ANOVA test for values to compare (e.g. number of differentially expressed genes) corresponding to different f ratio values (i.e. values of sequencing depth)

This function takes as input a dataframe containing the dataset to explore.

Here is the example of the dataframe

exploreRob function subsets the dataset to consider only valyes for one type of annotation and runs ANOVA test for groups corresponding to f values of interest.

Value
