xBiheatmap: Function to visualise bipartitle graph communities using heatmap

Description

xBiheatmap is supposed to visualise bipartitle graph communities using heatmap.

Usage

xBiheatmap(g, which.communites = NULL, colormap = "spectral",
ncolors = 64, zlim = NULL, barwidth = 0.3, barheight = NULL,
nbin = 64, legend.title = "", x.rotate = 60, x.text.size = 3,
y.text.size = 3, legend.text.size = 4, legend.title.size = 6,
shape = 19, size = 0.5, plot.margin = unit(c(5.5, 5.5, 5.5, 5.5),
"pt"),
font.family = "sans", na.color = "transparent",
intercept.color = "grey95", intercept.size = 0.3)

Arguments

g

an object of class "igraph" for a bipartitel graph with node attributes 'type', 'community' and 'contribution'

which.communites

a vector specifying which communites are visualised. If NULL (by default), all communites will be used

colormap

short name for the colormap. It can be one of "jet" (jet colormap), "bwr" (blue-white-red colormap), "gbr" (green-black-red colormap), "wyr" (white-yellow-red colormap), "br" (black-red colormap), "yr" (yellow-red colormap), "wb" (white-black colormap), and "rainbow" (rainbow colormap, that is, red-yellow-green-cyan-blue-magenta). Alternatively, any hyphen-separated HTML color names, e.g. "blue-black-yellow", "royalblue-white-sandybrown", "darkgreen-white-darkviolet". A list of standard color names can be found in http://html-color-codes.info/color-names

ncolors

the number of colors specified over the colormap

zlim

the minimum and maximum z values for which colors should be plotted, defaulting to the range of the finite values of displayed matrix

barwidth

the width of the colorbar. Default value is 'legend.key.width' or 'legend.key.size' in 'theme' or theme

barheight

the height of the colorbar. Default value is 'legend.key.height' or 'legend.key.size' in 'theme' or theme

nbin

the number of bins for drawing colorbar

legend.title

the title of the colorbar. By default, it is ''

x.rotate

the angle to rotate the x tick labelings. By default, it is 60

x.text.size

the text size of the x tick labelings. By default, it is 6

y.text.size

the text size of the y tick labelings. By default, it is 6

legend.text.size

the text size of the legend tick labelings. By default, it is 5

legend.title.size

the text size of the legend titles. By default, it is 6

shape

the number specifying the shape. By default, it is 19

size

the number specifying the shape size. By default, it is 2

plot.margin

the margin (t, r, b, l) around plot. By default, it is unit(c(5.5,5.5,5.5,5.5),"pt")

font.family

the font family for texts

na.color

the color for NAs. By default, it is 'grey80'

intercept.color

intercept color

intercept.size

intercept size

Value

a ggplot2 object

Examples

# NOT RUN {
# 1) generate a random bipartite graph
set.seed(123)
g <- sample_bipartite(100, 50, p=0.1)
V(g)$name <- paste0('node_',1:vcount(g))

# }
# NOT RUN {
# 2) obtain its community
ig <- xBigraph(g)

# 3) heatmap of its community
gp <- xBiheatmap(ig)
# }
