R语言中igraph绘制网络图

效果如下

library(igraph)

# Create data
set.seed(1)
data <- matrix(sample(0:1, 100, replace=TRUE, prob=c(0.8,0.2)), nc=10)
network <- graph_from_adjacency_matrix(data , mode='undirected', diag=F )

# Default network
par(mar=c(0,0,0,0))
opar <- par(no.readonly = T)
par(mfrow=c(2,2))
plot(network)

# Customize node features
plot(network,
     vertex.color = rgb(0.8,0.2,0.2,0.9),           # Node color
     vertex.frame.color = "Forestgreen",            # Node border color
     vertex.shape=c("circle","square"),             # One of “none”, “circle”, “square”, “csquare”, “rectangle” “crectangle”, “vrectangle”, “pie”, “raster”, or “sphere”
     vertex.size=c(15:24),                          # Size of the node (default is 15)
     vertex.size2=NA,                               # The second size of the node (e.g. for a rectangle)
)

# Customize label features
plot(network,
     vertex.label=LETTERS[1:10],                    # Character vector used to label the nodes
     vertex.label.color=c("red","blue"),
     vertex.label.family="Times",                   # Font family of the label (e.g.“Times”, “Helvetica”)
     vertex.label.font=c(1,2,3,4),                  # Font: 1 plain, 2 bold, 3, italic, 4 bold italic, 5 symbol
     vertex.label.cex=c(0.5,1,1.5),                 # Font size (multiplication factor, device-dependent)
     vertex.label.dist=0,                           # Distance between the label and the vertex
     vertex.label.degree=0 ,                        # The position of the label in relation to the vertex (use pi)
)

# Customize link features
plot(network,
     edge.color=rep(c("red","pink"),5),           # Edge color
     edge.width=seq(1,10),                        # Edge width, defaults to 1
     edge.arrow.size=1,                           # Arrow size, defaults to 1
     edge.arrow.width=1,                          # Arrow width, defaults to 1
     edge.lty=c("solid")                           # Line type, could be 0 or “blank”, 1 or “solid”, 2 or “dashed”, 3 or “dotted”, 4 or “dotdash”, 5 or “longdash”, 6 or “twodash”
     #edge.curved=c(rep(0,5), rep(1,5))            # Edge curvature, range 0-1 (FALSE sets it to 0, TRUE to 0.5)
)

自定义结果
