R/uniqueness_functions.R
uniqueness_prop.RdUse proportion of samples for which a mass/peak is present to compare two groups and determine which peaks are uniquely expressed in each group
uniqueness_prop(edata_df, group_df, data_scale, pres_thresh, absn_thresh)data.frame giving samples expression profiles for samples belonging to one of two groups
data.frame giving sample names and column indicating group membership. Column indicating group membership should be named 'Group' and have exactly two unique values
character string giving scale the data is on. Current acceptable values are: "log", "log2", "log10", "abundance", "pres"
numeric value between 0 and 1, inclusive, indicating the minimum proportion of samples per group that are required for a peak to be considered present/observed in a group.
numeric value between 0 and 1, inclusive, indicating the maximum proportion of samples per group that can be observed for a peak to be considered absent in a group.
