correspond_between_two_rankings(x1, x2, name1, name2,
    col1 = 2, col2 = 3, top_n = round(0.25*length(x1)), transparency = 0.9,
    pt_size = unit(1, "mm"), newpage = TRUE, ratio = c(1, 1, 1))

Arguments

x1

A vector of scores calculated by one metric.

x2

A vector of scores calculated by another metric.

name1

Name of the first metric.

name2

Name of the second metric.

col1

Color for the first metric.

col2

Color for the second metric.

top_n

Top n elements to show the correspondance.

transparency

Transparency of the connecting lines.

pt_size

Size of the points, must be a unit object.

newpage

Whether to plot in a new graphic page.

ratio

Ratio of width of the left barplot, connection lines and right barplot. The three values will be scaled to a sum of 1.

Details

In x1 and x2, the i^th element in both vectors corresponds to the same object (e.g. same row if they are calculated from a matrix) but with different scores under different metrics.

x1 and x2 are sorted in the left panel and right panel respectively. The top n elements under corresponding metric are highlighted by vertical colored lines in both panels. The left and right panels also shown as barplots of the scores in the two metrics. Between the left and right panels, there are lines connecting the same element (e.g. i^th element in x1 and x2) in the two ordered vectors so that you can see how a same element has two different ranks in the two metrics.

Under the plot is a simple Venn diagram showing the overlaps of the top n elements by the two metrics.

Value

No value is returned.
