In stemangiola/ttSc: Friendly tidy wrappers for facilitating transcriptional analyses

Add differential transcription information to a tbl using Seurat

Description

test_differential_abundance() takes as imput a 'tbl' formatted as | <SAMPLE> | <TRANSCRIPT> | <COUNT> | <...> | and returns a 'tbl' with additional columns for the statistics from the hypothesis test.

Usage

test_differential_abundance(.data, .formula, significance_threshold = 0.05)

Arguments

.data	A 'tbl' formatted as | <SAMPLE> | <TRANSCRIPT> | <COUNT> | <...> |
.formula	A formula with no response variable, representing the desired linear model
significance_threshold	A real between 0 and 1 (usually 0.05).
.sample	The name of the sample column
.transcript	The name of the transcript/gene column
.abundance	The name of the transcript/gene abundance column
action	A character string. Whether to join the new information to the input tbl (add), or just get the non-redundant tbl with the new information (get).

experimental

At the moment this function uses edgeR only, but other inference algorithms will be added in the near future.

Value

A 'tbl' with additional columns for the statistics from the hypothesis test (e.g., log fold change, p-value and false discovery rate).
