人工设置网络模块位置2-大尺度空间网络布局应用

写在前面

多变形排布，将不同的模块按照多变形排布进行。模块越大的部分，其半径越大，是按照模块内节点数量判断到多变形中心的距离。

微生物网络

输入文件

#--导入所需R包#-------
library(igraph)
library(sna)
library(ggplot2)
library(ggClusterNet)
library(phyloseq)
#-----导入数据#-------
ps = readRDS("../ori_data/ps_liu.rds")
ps

corMicro函数用于计算相关

按照丰度过滤微生物表格，并却计算相关矩阵，按照指定的阈值挑选矩阵中展示的数值。

#-----微生物网络构建参数设置#----
#-提取丰度前百分之多少的otu进行构建网络
# N = 0.02
# r.threshold=0.6
# p.threshold=0.05

#----------计算相关#----
result = corMicro (ps = ps,N = 0.02,r.threshold=0.8,p.threshold=0.05,method = "pearson")

#--提取相关矩阵
cor = result[[1]]
# head(cor)

制作分组

这是网络布局的基础，无论是什么聚类布局，都需要制作一个分组文件，这个文件有两列，一列是节点，一列是分组信息，这个分组信息名称为：group。

#-提取tax注释文件，用于分组#-----
vegan_otu <- function(physeq){
OTU <- otu_table(physeq)
if(taxa_are_rows(OTU)){
OTU <- t(OTU)
}
return(as(OTU,"matrix"))
}

ps_net = result[[3]]
otu_table = as.data.frame(t(vegan_otu(ps_net)))

vegan_tax <- function(physeq){
tax <- tax_table(physeq)

return(as(tax,"matrix"))
}
tax_table = as.data.frame(vegan_tax(ps_net))

netClu = data.frame(ID = row.names(tax_table),group =rep(1:5,length(row.names(tax_table)))[1:length(row.names(tax_table))] )
netClu$group = as.factor(netClu$group)
head(netClu)

人工指定分组

##-----人工置顶半径大小和圆心位置

#--这里我设置r都是相同的，也可以设置不同，然后包装成一个向量就可以了#-------
xs = as.data.frame(table(netClu$group))
r = rep(4,length(xs$Freq))
r
#----准备圆心坐标，往往与你的设计有关#---------
# 有多少个模块就提供多少个坐标
#--指定坐标吮顺序按照一下指定
xs$Var1
#-------人工准备坐标
ax1 = c(80,40)
ax2 = c(90,30)
ax3 = c(110,40)
ax4 = c(130,50)
ax5 = c(110,10)

da = rbind(ax1,ax2,ax3,ax4,ax5)

rArtifCluster根据分组，人工指定布局

?ArtifCluster
#--------计算布局#---------
#-------计算网络布局-得到节点坐标=node#---------
result2 = ArtifCluster(cor = cor,nodeGroup =netClu,r = r,da =da)

node = result2[[1]]
head(node)

### nodeadd 节点注释的简单封装，便捷实用otu表格和分组文件进行注释

#---node节点注释#-----------
nodes = nodeadd(plotcord =node,otu_table = otu_table,tax_table = tax_table)
head(nodes)

#-----计算边#--------
edge = edgeBuild(cor = cor,plotcord = node)

head(edge)

ggplot()+ geom_segment(aes(x = X1, y = Y1, xend = X2, yend = Y2,color = as.factor(wei_label)),

scale_x_continuous(breaks = NULL) + scale_y_continuous(breaks = NULL)
