Extract a subset population — significance

Subsets data according to the significance groups.

significance_subset(polar, significance = NULL, output = "pvals")

Arguments

polar	A polar object including expression data from groups of interest. Created by `polar_coords`.
significance	Which significance factors to subset to. If `NULL` all levels except 'ns' (non-significant) are selected.
output	What object to return. Options are "pvals", "padj", "data", "df" for subset dataframes, or "polar" to subset the entire 'volc3d' class object.

Value

Returns an object (type defined by output) with rows susbet to those which satisfy the significance condition.
