Subscript out of bounds error when using an adjacency matrix in r -


i error when applying function adjacency matrix in r.

the adjacency matrix looks this:

s2     1   2   3   4   5   7   8   9   6 1   0   1   2   3   3   0   0   0   0 2   1   0   0   0   1   1   2   2   0 3   2   0   0   0   0   1   0   4   2 4   3   0   0   0   0   0   0   0   0 5   3   1   0   0   0   0   0   0   0 7   0   1   1   0   0   0   0   0   0 8   0   2   0   0   0   0   0   0   0 9   0   2   4   0   0   0   0   0   0 6   0   0   2   0   0   0   0   0   0

the code follows:

library(igraph)  library(egonet)  x<-index.egonet(s2)

when apply index.egonet gives me error subscript out of bounds.

any or solution problem highly appreciated.

your ego subject (parameter ego.name) not defined.

the following, defining first person ego person works: 

library(igraph) library(egonet) s2 <- c(0,1,2,3,3,0,0,0,0, 1,0,0,0,1,1,2,2,0, 2,0,0,0,0,1,0,4,2, 3,0,0,0,0,0,0,0,0, 3,1,0,0,0,0,0,0,0, 0,1,1,0,0,0,0,0,0, 0,2,0,0,0,0,0,0,0, 0,2,4,0,0,0,0,0,0, 0,0,2,0,0,0,0,0,0) s2 <- matrix(s2,nrow=9)  colnames(s2) <- rownames(s2) <- paste0(as.character(c(1:5,7:9,6))) x<-index.egonet(s2,ego.name = "1")

Email notification in google apps script -

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
