Converting edgelist to symmetric matrix
...and y represents column
header. All edgelists are based on links among 634 nodes and I need to convert
them into a 634*634 weighted matrix.
I searched for online help using possible keywords I know, but I could not find
a clue how to do this in R. Any help will be appreciated.
Best regards,
Shafique

Problem in conditional looping
...with negitive sign and ultimately
resulted in an negative variance estimator. Now i want to design the
program like this if the Pij is negative then go back and draw another
sample until we get a sample that produces positive Pij and then move
forward for further processing.

Problem in applying conditional looping
...)
var1 <- E2yht - Eyht^2
var1
}
I want to impose the condition on PIJ(which is a vector). If any value in
the PIJ is negative then go back and take another sample until a sample is
selected which produces the PIJ positive(all values in PIJ).
I hope now you can understand.

Listing all possible samples of Size two form Large Population
...possible samples but it hangs my computer for larger populations
say 10,000 (i.e. 49995000 all possible samples). I wish to even work
for larger populations then this and replicate this procedure for many
times. Kindly can anyone figure out the possibilities and let me know.
