elbow_curve: Elbow curve for a ranking

In strayMat/lineageDE: Differentially expressed genes in cell lineages

Description

Plot an elbow curve of the distribution of distances from a rankingDE. It gives an idea of the shape of the distribution and can help select a threshold for the differntially expressed genes.

Usage

elbow_curve(ranking, xmax = nrow(ranking), xfit = 0.005 * nrow(ranking))

Arguments

ranking	a rankingDE object.
xmax	integer, at which rank we cut off the curve. (default is length(ranking))
xfit	integer, cutoff for the plot of the tangent at the origin (default is 0.005*length(ranking)).

Value

returns

• a plot of the distances against the ranks of the elements in the ranking.

• rank threshold
