Value

A ggplot2 object or NULL if no ranking was conducted.

Arguments

...

A single netrank object or a list of netrank objects.

name

An optional character vector providing descriptive names for the network meta-analysis objects.

common

A logical indicating whether results for the common effects model should be plotted.

random

A logical indicating whether results for the random effects model should be plotted.

seq

A character or numerical vector specifying the sequence of treatments on the x-axis.

low

A character string defining the colour for a P-score of 0, see scale_fill_gradient2.

mid

A character string defining the colour for a P-score of 0.5, see scale_fill_gradient2.

high

A character string defining the colour for a P-score of 1, see scale_fill_gradient2.

col

Colour of text.

main

Title.

main.size

Font size of title, see element_text.

main.col

Colour of title, see element_text.

main.face

Font face of title, see element_text.

legend

A logical indicating whether a legend should be printed.

axis.size

Font size of axis text, see element_text.

axis.col

Colour of axis text, see element_text.

axis.face

Font face of axis text, see element_text.

na.value

Colour for missing values, see scale_fill_gradient2.

angle

Angle for text on x-axis, see element_text.

hjust.x

A numeric between 0 and 1 with horizontal justification of text on x-axis, see element_text.

vjust.x

A numeric between 0 and 1 with vertical justification of text on x-axis, see element_text.

hjust.y

A numeric between 0 and 1 with horizontal justification of text on y-axis, see element_text.

vjust.y

A numeric between 0 and 1 with vertical justification of text on y-axis, see element_text.

nchar.trts

A numeric defining the minimum number of characters used to create unique treatment names.

digits

Minimal number of significant digits, see print.default.

fixed

Deprecated argument (replaced by 'common').

comb.fixed

Deprecated argument (replaced by 'common').

comb.random

Deprecated argument (replaced by 'random').

warn.deprecated

A logical indicating whether warnings should be printed if deprecated arguments are used.

Details

This function produces an image plot of network rankings (Palpacuer et al., 2018, Figure 4). Note, a scatter plot of two network rankings can be generated with plot.netposet.

By default, treatments are ordered by decreasing P-scores of the first network meta-analysis object. Argument seq can be used to specify a differenct treatment order.
