as shown in the code, four variables input: diff_expr,diff_coex, klist,
Pop_size, are included in the function. However, within the function,
another variable "vector" is utilized in some subfunction. How they get its
value?
thx
get_quantiles <-function(diff_expr,diff_coex,klist,pop_size){
##### The function to get the "node_score_term" and "edge_score_term" of a
sub-network denoted by "vector"
my.fun<-function(vector){
return(diff_coex[vector[1],vector[2]])
}
# "vector" is a binary vector with length equal to the size of the whole
network.
# An element of value "1" indicates the inclusion of that gene in the
selected sub-network.
node_edge<-function(vector){
selected_subset<-which(vector==1)
n<-length(selected_subset)
node_score<-sum(diff_expr[selected_subset])/sqrt(n)
edges<-combn(selected_subset,2)
edge_score<-sum(apply(edges,2,my.fun))/sqrt(choose(n,2))
return(c(node_score,edge_score))
}
}
