Filter views with not enough features

filt_views_bygenes.Rd

Filter complete views based on their number of profiled features

Usage

filt_views_bygenes(pb_dat_list, ngenes)

Arguments

pb_dat_list

List of SummarizedExperiment generated from MOFAcellulaR::filt_profiles()

ngenes

Numeric, minimum number of features per view.

Value

A named list of SummarizedExperiments per cell type provided with filtered pseudobulk profiles

Details

This function allows the user to control the number of minimum features per view

Examples

inputs_dir <- base::system.file("extdata", package = "MOFAcellulaR")
load(file.path(inputs_dir, "testpbcounts.rda"))
load(file.path(inputs_dir, "testcoldata.rda"))

pb_obj <- create_init_exp(counts = testpbcounts,
                          coldata = testcoldata)

ct_list <- filt_profiles(pb_dat = pb_obj,
                         cts = c("Fib","CM"),

                         ct_col = "cell_type")

                           min.prop = 0.25)
