bbplot1dR Documentation

Plot of metapone result.

Description

The function bbplot1d() select important pathways with their P-value less than a threshold and returns ranked bubble plot showing important pathways names and their corresponding -log10(Pvalue).

Usage

bbplot1d(res, p_thres = 0.05, sig_metab_thres = 1, low.color = "MidnightBlue", high.color = "LightSkyBlue")

Arguments

res

The result matrix obtained from metapone with columns: "p_value", "n_significant metabolites", "n_mapped_metabolites", "n_metabolites", "significant metabolites", "mapped_metabolites", "fdr".

p_thres

The threshold of P-value for pathways to be shown in the bubble plot. The default threshold is 0.05.

sig_metab_thres

The threshold of fractional matched significant metabolite count for pathways to be shown in the bubble plot. The default is 1.

low.color

The GRB color of the lowest ldfr value to be shown in the bubble plot.

high.color

The GRB color of the highest ldfr value to be shown in the bubble plot.
