Why R claims: "Error in if (S[i, j] == S[j, i]) { : missing value where TRUE/FALSE needed ? Symmetric Matrix

Here is my code: Sip<-function(S,u,v){ S<-matrix(,u,v);u<-nrow(S);v<-ncol(S);u==v; for(i in 1:u) {for(j in 1:v){ if(S[i,j]==S[j,i]){print("Simétrica")} else{print("No simétrica")} } } S } Sip(S,2,2) My error is…
