bubble_plot: Bubble plot of CMap output table

Description

This function allows the user to represent the Connectivity Map (CMap) result table (broadinstitute) under the form of a bubble plot representing statistics and cell lines: - each drug is represented along the y axis according to its enrichment value - each drug is represented along the x axis according to the cell line tested and within the cell line according to batch specificity (0-50

Usage

bubble_plot(path, plot, enrichment, abs.enrich.cutoff=NULL, n.rep.cutoff=NULL ,
        jittering=FALSE, return.gg.table= FALSE, output_path = NULL)

Arguments

path

path of the excel file (permutated results)

plot

what data to plot: molecules only (plot="molecules") or molecules by cell lines batch (plot="cell.lines")

enrichment

whether to plot positive or negative enrichment

abs.enrich.cutoff

minimum value of enrichment to include a batch

n.rep.cutoff

minimum number of replicates to include a batch (default=NULL)

jittering

whether apply jittering to the values to avoid points overlap

return.gg.table

table prepared for ggplot, allows the user to customize the graphical representation

output_path

path for the experiment output folder, returns data table and figure (default=NULL)

Value

ggplot object - bubble plot

Examples

# NOT RUN {
file.path <- system.file("extdata", "example.xls", package = "CMapViz")
#display results by cell lines, with negative enrichment (absolute cutoff: 0.5), and at least n=5.
#molecule position with respect of dotted line is the specificity of the molecule itself:
#left side of dotted line if specificity < 50 or right side of dotted line if specificity > 50 )
bubble_plot(file.path,
    plot = "cell.lines", enrichment = "negative", abs.enrich.cutoff = 0.5,
    n.rep.cutoff = 5, output_path = NULL
)
# }
