PlotSourceContribution: PlotSourceContribution

In wsteenhu/FEAST: FEAST: fast expectation-maximization for microbial source tracking

Description

Save a stacked barplot of source contributions to a group of pre-defined sink samples, sharing the same sources.

Usage

PlotSourceContribution(SinkNames, SourceNames, Same_sources_flag,
  mixing_proportions, dir_path, Plot_title = "Example", N)

Arguments

SinkNames	A vector with the sink names to plot.
SourceNames	A vector with all the sources' names.
Same_sources_flag	A boolian value indicating the source-sink plotting assignment. Same_sources_flag = 1 if the same sources are assigned to the pre-defined sink samples , otherwise = 0.
mixing_proportions	A list of vectors, where entry i corresponds to the vector of source contributions (summing to 1) to sink i.
dir_path	A path to an output .png file.
Plot_title	Plot's title and output .png file's name.
N	Number of barplot in each output .png file.

Examples

#Load metadata table

#Load count matrix

#Calculate the sources' contributions to
#each sink sample in the data
FEAST_output <- FEAST(count_matrix = otus, metadata = metadata,
                     different_sources_flag = 1)

#Plot and save a stacked barplot of source contributions
#to the first four sink samples
PlotSourceContribution(SinkNames, SourceNames, Same_sources_flag,
                      mixing_proportions, dir_path, Plot_title = "Example",N)
