fix_frq_df: fix_frq_df

In saeyslab/muscatWrapper: Wrapper functions around muscat for differential expression analysis of multi-sample multi-condition scRNAseq datasets

fix_frq_df

Description

fix_frq_df Fix muscat-bug in fraction calculation in case that expression fraction would be NA / NaN. Change NA to 0.

Usage

fix_frq_df(sce, frq_celltype_samples)

Arguments

sce	SingleCellExperiment object of the scRNAseq data of interest.
frq_celltype_samples	Sample-average data frame output of 'get_muscat_exprs_frac'

Value

Fixed data frame with fraction of cells expressing a gene.

Examples

if(nrow(frq_df %>% dplyr::filter(is.na(fraction_sample))) > 0 | nrow(frq_df %>% dplyr::filter(is.nan(fraction_sample))) > 0) {
  frq_df = fix_frq_df(sce, frq_df)
